Book Description
"On 12 February 2006, the recurrent nova RS Ophiuchi erupted for the first time since 1985, its 6th (at least!) known eruption. This event triggered an intensive multi-wavelength observational campaign, from the radio to gamma-rays, and theoreticians have been presented with a wealth of high-quality data. A workshop was held at Keele University, UK, from 12-14 June 2007 to discuss the observations, their interpretation, and where RS Ophiuchi sits in the wider astrophysical picture. The workshop brought together observers, from gamma-ray to radio wavelengths, theoreticians, and workers in closely related areas. The workshop considered not only the 2006 eruption of RS Oph but also the implications that this has had for our understanding of other much broader areas of astrophysics. It was wide ranging, taking in the environments of red giants; supernova progenitors; accretion, thermonuclear processes and evolution of close binary systems; and shocks of jets, as well as recurrent novae and related objects. The proceedings contain 15 invited reviews, 38 contributed talks and posters, and 3 specially commissioned papers which we hope will enhance the value of the workshop for the wider astrophysical community."--Publisher's website

Supernova Explosions
Author: David Branch
Publisher: Springer
ISBN: 3662550547
Category : Science
Languages : en
Pages : 719
Book Description
Targeting advanced students of astronomy and physics, as well as astronomers and physicists contemplating research on supernovae or related fields, David Branch and J. Craig Wheeler offer a modern account of the nature, causes and consequences of supernovae, as well as of issues that remain to be resolved. Owing especially to (1) the appearance of supernova 1987A in the nearby Large Magellanic Cloud, (2) the spectacularly successful use of supernovae as distance indicators for cosmology, (3) the association of some supernovae with the enigmatic cosmic gamma-ray bursts, and (4) the discovery of a class of superluminous supernovae, the pace of supernova research has been increasing sharply. This monograph serves as a broad survey of modern supernova research and a guide to the current literature. The book’s emphasis is on the explosive phases of supernovae. Part 1 is devoted to a survey of the kinds of observations that inform us about supernovae, some basic interpretations of such data, and an overview of the evolution of stars that brings them to an explosive endpoint. Part 2 goes into more detail on core-collapse and superluminous events: which kinds of stars produce them, and how do they do it? Part 3 is concerned with the stellar progenitors and explosion mechanisms of thermonuclear (Type Ia) supernovae. Part 4 is about consequences of supernovae and some applications to astrophysics and cosmology. References are provided in sufficient number to help the reader enter the literature.

High-Precision Studies of Compact Variable Stars
Author: Steven Bloemen
Publisher: Springer
ISBN: 3319102834
Category : Science
Languages : en
Pages : 138
Book Description
This book, which is a reworked and updated version of Steven Bloemen’s original PhD thesis, reports on several high-precision studies of compact variable stars. Its strength lies in the large variety of observational, theoretical and instrumentation techniques that are presented and used and paves the way towards new and detailed asteroseismic applications of single and binary subdwarf stars. Close binary stars are studied using high cadence spectroscopic datasets collected with state of the art electron multiplying CCDs and analysed using Doppler tomography visualization techniques. The work touches upon instrumentation, presenting the calibration of a new fast, multi-colour camera installed at the Mercator Telescope on La Palma. The thesis also includes theoretical work on the computation of the temperature range in which stellar oscillations can be driven in subdwarf B-stars. Finally, the highlight of the thesis is the measurement of velocities of stars using only photometric data from NASA's Kepler satellite. Doppler beaming causes stars to appear slightly brighter when they move towards us in their orbits, and this subtle effect can be seen in Kepler's brightness measurements. The thesis presents the first validation of such velocity measurements using independent spectroscopic measurements. Since the detection and validation of this Doppler beaming effect, it has been used in tens of studies to detect and characterize binary star systems, which are key calibrators in stellar astronomy.

Pulsating Stars
Author: Márcio Catelan
Publisher: John Wiley & Sons
ISBN: 3527655204
Category : Science
Languages : en
Pages : 500
Book Description
This book surveys our understanding of stars which change in brightness because they pulsate. Pulsating variable stars are keys to distance scales inside and beyond the Milky Way galaxy. They test our understanding not only of stellar pulsation theory but also of stellar structure and evolution theory. Moreover, pulsating stars are important probes of the formation and evolution of our own and neighboring galaxies. Our understanding of pulsating stars has greatly increased in recent years as large-scale surveys of pulsating stars in the Milky Way and other Local Group galaxies have provided a wealth of new observations and as space-based instruments have studied particular pulsating stars in unprecedented detail.

RS Ophiuchi (1985) and the Recurrent Nova Phenomenon
Author: M. F. Bode
Publisher: VSP
ISBN: 9789067640749
Category : Science
Languages : en
Pages : 276
Book Description
This international conference brought together over 50 astronomers from around the world. The meeting centred around a single object, the reccurent nova RS Ophiuchi, a star which had undergone four recorded outbursts before the latest event in 1985. Observations of previous outbursts (discussed in detail in one of the review talks) already indicated that RS Ophiuchi is a unique object of great astronomical significance. The outburst mechanism is probably similar to that of classical novae, but the interaction of the ejecta with a pre-existing shell of material give it the characteristics of a young supernova remnant. However, unlike supernova remnants, the evolution occurs 'before our very eyes'. Following the latest outburst, a frenzy of activity ensued, resulting in the acquisition of detailed observations from the radio (where rapidly expanding jets were discovered) to the X-ray (where RS Ophiuchi turned out to be one of the brightest soft X-ray sources yet observed). The Proceedings report the many exciting and unexpected observational results right across the electromagnetic spectrum in both RS Ophiuchi and related objects. Theoretical work on the cause of the outburst, and remnant evolution is also given prominence. The result is a much fuller understanding of RS Ophiuchi and its important standing in several branches of astrophysical research.

Cataclysmic Cosmic Events and How to Observe Them
Author: Martin Mobberley
Publisher: Springer Science & Business Media
ISBN: 038779946X
Category : Science
Languages : en
Pages : 247
Book Description
In the Victorian era – or for non-British readers, the mid-to-late nineteenth century – amateur astronomy tended to center on Solar System objects. The Moon and planets, as well as bright comets, were the key objects of interest. The brighter variable stars were monitored, but photography was in its infancy and digital imaging lay a century in the future. Today, at the start of the twenty-first century, amateurs are better equipped than any professionals of the mid-twentieth century, let alone the nineteenth. An amateur equipped with a 30-cm telescope and a CCD camera can easily image objects below magnitude 20 and, from very dark sites, 22 or 23. Such limits would have been within the realm of the 100- and 200-inch reflectors on Mount Wilson and Mount Palomar in the 1950s, but no other observatories. However, even those telescopes took hours to reach such limits, and then the photographic plates had to be developed, fixed, and examined by eye. In the modern era digital images can be obtained in minutes and analyzed ‘on the fly’ while more images are being downloaded. Developments can be e-mailed to other interested amateurs in real time, during an observing session, so that when a cataclysmic event takes place amateurs worldwide know about it. As recently as the 1980s, even professional astronomers could only dream of such instantaneous communication and proc- sing ability.
