Book Description
Ultraviolet Astronomy and the Quest for the Origin of Life addresses the use of astronomical observations in the ultraviolet range to better understand the generation of complex, life-precursor molecules. The origin of RNA is still under debate but seems to be related to the generation of pools of complex organic molecules submitted to heavy cycles of solution in water and drying. This book investigates whether these cycles require a planetary surface or may occur in space by examining both the theoretical and observational aspects of the role of UV radiation in the origin of life. This book offers the latest advances in these studies for astronomers, astrobiologists and planetary scientists. - Addresses both the theoretical and observational aspects of the role of Ultraviolet (UV) radiation in the origin of life - Builds on the requirements to produce prebiotic molecules in space and the implications for the origin of RNA - Investigates the use of ultraviolet observations related to planetary system formation, the evolution of young planetary disks, and the interaction of stars with planetary atmospheres

Book Description
Written by leading experts in the field, Stellar Spectral Classification is the only book to comprehensively discuss both the foundations and most up-to-date techniques of MK and other spectral classification systems. Definitive and encyclopedic, the book introduces the astrophysics of spectroscopy, reviews the entire field of stellar astronomy, and shows how the well-tested methods of spectral classification are a powerful discovery tool for graduate students and researchers working in astronomy and astrophysics. The book begins with a historical survey, followed by chapters discussing the entire range of stellar phenomena, from brown dwarfs to supernovae. The authors account for advances in the field, including the addition of the L and T dwarf classes; the revision of the carbon star, Wolf-Rayet, and white dwarf classification schemes; and the application of neural nets to spectral classification. Copious figures illustrate the morphology of stellar spectra, and the book incorporates recent discoveries from earth-based and satellite data. Many examples of spectra are given in the red, ultraviolet, and infrared regions, as well as in the traditional blue-violet optical region, all of which are useful for researchers identifying stellar and galactic spectra. This essential reference includes a glossary, handy appendixes and tables, an index, and a Web-based resource of spectra. In addition to the authors, the contributors are Adam J. Burgasser, Margaret M. Hanson, J. Davy Kirkpatrick, and Nolan R. Walborn.

Book Description
In the magical time between night and day, when both the sun and the moon are in the sky, a child is born in a little blue house on a hill. And Miu Lan is not just any child, but one who can change into any shape they can imagine. The only problem is they can't decide what to be: A boy or a girl? A bird or a fish? A flower or a shooting star? At school, though, they must endure inquisitive looks and difficult questions from the other children, and they have trouble finding friends who will accept them for who they are. But they find comfort in the loving arms of their mother, who always offers them the same loving refrain: "whatever you dream of / i believe you can be / from the stars in the sky to the fish in the sea." In this captivating, beautifully imagined picture book about gender, identity, and the acceptance of the differences between us, Miu Lan faces many questions about who they are and who they may be. But one thing's for sure: no matter what this child becomes, their mother will love them just the same. Kai Cheng Thom is a writer, performance artist, and psychotherapist in Toronto. Her first poetry book, a Place Called No Homeland, was published in 2017. Kai Yun Ching is a community-based organizer, educator, and illustrator in Montreal. Wai-Yant Li is a ceramics artist and illustrator in Montreal.

Tattoos with hearts, minds, and dreams. Created to be the armor that protects my body, these obsidian shadows come alive at night—demons made flesh. After the Aetar nearly kill Maxine’s unborn child, and a betrayal within her own ranks leaves Maxine’s husband, Grant, poisoned and dying, Maxine is forced to attack a race of beings that possesses almost unlimited power. Doing so will require she make a deal with the devil—the devil that lives inside her—risking both her sanity and her soul as she slowly transforms into something more than human. But even that might not be enough to save Grant, because the very thing that Maxine is becoming is destined to destroy the world.

“It’s fun to find ways I’m like you and you’re like me. It’s fun to find ways we’re different.” In this colorful, inviting book, kids from preschool to lower elementary learn about diversity in terms they can understand: hair that’s straight or curly, families with many people or few, bodies that are big or small. With its wide-ranging examples and fun, highly detailed art, I’m Like You, You’re Like Me helps kids appreciate the ways they are alike and affirm their individual differences. A two-page adult section in the back provides tips and activities for parents and caregivers to reinforce the themes and lessons of the book.
