Book Description
Excerpt from The Astrophysical Journal, Vol. 37: An International Review of Spectroscopy and Astronomical Physics; January-June, 1913 The unique behavior of the sharp calcium line K as shown in radial velocity investigations of a certain class of stars was first noted by Hartmann in a discussion of the spectrum and the orbit of δ Orionis. The large range, something over 200 km, indicated by the broad lines of this star made the comparatively constant velocity of the K line of calcium stand out prominently. Hartmann's conclusion that his range of values for K, 21 km, was due to general errors of observation has been questioned by Frost and Adams. His hypothesis that the calcium line K as photographed in the spectrum of δ Orionis is due to a calcium cloud lying in the line of sight at some point between the solar system and this star has not been disproved and constitutes a part of the history of stellar spectroscopy. Since that time considerable attention has been given to stars of the early spectral types which have sharp H and K lines, and a list of objects known to belong to this class would at the present time include a hundred or more stars.

Book Description
This research monograph presents a new dynamical framework for the study of secular morphological evolution of galaxies along the Hubble sequence. Classical approaches based on Boltzmann’s kinetic equation, as well as on its moment-equation descendants the Euler and Navier-Stokes fluid equations, are inadequate for treating the maintenance and long-term evolution of systems containing self-organized structures such as galactic density-wave modes. A global and synthetic approach, incorporating correlated fluctuations of the constituent particles during a nonequilibrium phase transition, is adopted to supplement the continuum treatment. The cutting-edge research combining analytical, N-body simulational, and observational aspects, as well as the fundamental-physics connections it provides, make this work a valuable reference for researchers and graduate students in astronomy, astrophysics, cosmology, many-body physics, complexity theory, and other related fields.

Book Description
In the summer and autumn of 2006 I read several interviews with Brian May in which he mentioned his desire to complete the PhD that he had abandoned in 1974. I looked up the papers he had published while a PhD student, which were on spectroscopic studies of the motion of the dust responsible for the zodiacal light, and felt that there was a basis for a thesis. Since he had been a student at Imperial, I knew, as Head of the Astrophysics Group at Imperial, that it would be good for the Group if he came and worked with us. I got in touch with him by email and suggested he come and talk about it. He replied enthusiastically and said that he was working on typing up what he had completed by 1974. I gradually realized that I was the only staff member at Imperial who had previously worked on zodiacal dust, so that I would have to act as his supervisor. Eventually we met and I tried to assess whether he would be able to find time for the huge amount of work that finishing off a thesis involves, particularly if it has not been touched for over 30 years. Since some of Brian’s emails were coming from the recording studio I knew there was strong competition for his time.
