Space Encyclopedia, 2nd Edition: A Tour of Our Solar System and Beyond

為了解決Kuiper System的問題，作者Aguilar, David A.,Daniels, Patricia 這樣論述：

Blast off into space with the experts at National Geographic to discover everything we know about the universe, including exciting, recent discoveries and amazing brand-new NASA space photography.The updated and expanded edition of the hit Space Encyclopedia presents the most up-to-date findings on

space exploration and research and breathtaking views of the universe, as captured by the latest and greatest technology, including the recent first ever image of a black hole. This complete reference contains everything kids need to know about our sun and planets including the new dwarf planets, th

e formation of the universe, space travel, the possibility of life beyond Earth, and more. Authored by David A. Aguilar, an internationally recognized astronomer and former Director of Science Information and Public Outreach at the Harvard-Smithsonian Center for Astrophysics, it is an authoritative

and beautifully illustrated must-have for every family, providing both accessible information for school reports and compelling reading on the mysteries beyond our planet. DAVID A. AGUILAR is an internationally recognized astronomer. He is the author and space artist of nine National Geographic an

d three Random House award-winning books, including: 7 Wonders of the Milky Way, a lively galactic journey through our home in the cosmos and Luna: The Science and Stories of Our Moon. He is an on-screen contributor and space artist for the History Channel’s Universe series, the Science Channel’s NA

SA’s Unexplained Files, and the NHK (Japanese National Television Corporation) Cosmic Front series. In 2015, he joined NASA’s New Horizons Mission Team as part of the historic Pluto Mission, and later in 2018-19, the Ultima Thule Kuiper Belt (KBO) Flyby Mission. In 2010, Asteroid 1990DA was named t

o honor his exceptional decades-long work to advance science education outreach. CHRISTINE PULLIAM is the news director for the Space Telescope Institute in Baltimore, MD, and the past manager of media relations for the Harvard-Smithsonian Center for Astrophysics in Cambridge, MA. In her spare time,

she flies airplanes. PATRICIA DANIELS has written more than a dozen science and history books for adults and children, including the National Geographic Encyclopedia of Space and Constellations: My First Pocket Guide.

Chasing New Horizons: Inside the Epic First Mission to Pluto

為了解決Kuiper System的問題，作者Stern, Alan,Grinspoon, David 這樣論述：

Called "spellbinding" (Scientific American) and "thrilling...a future classic of popular science" (Publishers Weekly), the up close, inside story of the greatest space exploration project of our time, New Horizons' mission to Pluto, as shared with David Grinspoon by mission leader Alan Stern and oth

er key players.On July 14, 2015, something amazing happened. More than 3 billion miles from Earth, a small NASA spacecraft called New Horizons screamed past Pluto at more than 32,000 miles per hour, focusing its instruments on the long mysterious icy worlds of the Pluto system, and then, just as qui

ckly, continued on its journey out into the beyond.Nothing like this has occurred in a generation--a raw exploration of new worlds unparalleled since NASA's Voyager missions to Uranus and Neptune--and nothing quite like it is planned to happen ever again. The photos that New Horizons sent back to Ea

rth graced the front pages of newspapers on all 7 continents, and NASA's website for the mission received more than 2 billion hits in the days surrounding the flyby. At a time when so many think that humankind's most historic achievements are in the past, the most distant planetary exploration ever

attempted not only succeeded but made history and captured the world's imagination.How did this happen? Chasing New Horizons is the story of the men and women behind this amazing mission: of their decades-long commitment and persistence; of the political fights within and outside of NASA; of the she

er human ingenuity it took to design, build, and fly the mission; and of the planning for New Horizons' second act, the amazing January 1, 2019 flyby of Ultima Thule, another billion miles beyond Pluto. Told from the insider's perspective of mission leader Dr. Alan Stern and others on New Horizons,

Chasing New Horizons is a riveting account of scientific discovery, and of how much we humans can achieve when people focused on a dream work together toward their incredible goal. DR. ALAN STERN is principal investigator of the New Horizons mission, leading NASA’s exploration of the Pluto system

and the Kuiper Belt. A planetary scientist, space-program executive, aerospace consultant, and author, he has participated in over two dozen scientific space missions and has been involved at the highest levels in several aspects of American space exploration. Dr. Stern is the recipient of numerous

awards, including the 2016 Carl Sagan Memorial Award of the American Astronautical Society, and has twice been named to the Time 100. He lives in Colorado.DR. DAVID GRINSPOON is an astrobiologist, award-winning science communicator, and prize-winning author. In 2013 he was appointed the inaugural ch

air of astrobiology at the Library of Congress. He is a frequent advisor to NASA on space-exploration strategy, and is on the science teams for several interplanetary spacecraft missions. Grinspoon’s previous books include Earth in Human Hands (2016) and his writing has appeared inTheNew York Times,

Slate, ScientificAmerican, Los Angeles Times, and others. He lives in Washington, DC.

大質量原恆雙星系統IRAS17216-3801周圍之雙星周盤

為了解決Kuiper System的問題，作者李昀安 這樣論述：

大質量聯星系統可能形成自不同的機制，例如：盤面分裂、紊流分裂或其他情境，然而，一個系統真實的形成機制很難從為數不多的觀測資料中判斷出來。這邊我們從ALMA的資料庫中選定大質量原恆雙星系統IRAS17216-3801，發表波段位於350GHz的連續譜線和光譜。此資料無法解析雙星系統中由Kraus et al. 2017所發現的各個星體，位於東邊的團塊則是第一次被觀測到，其擁有的分子豐富度比主目標來的少。主目標的光譜主要由一氧化硫及二氧化硫所組成，另外也有甲醇、氰化氫、HCO+分子以及他們的類同位素分子，我們利用二氧化硫和甲醇計算了旋轉能階溫度約為25-178K。許多分子（特別是二氧化硫）都在主

目標上呈現出旋轉結構，我們認為這些分子追蹤了圍繞在原恆雙星周圍的雙星周盤，我們利用多組不同能量躍遷的二氧化硫與克卜勒薄盤面模型進行資料擬合來限制雙星周盤的幾何與動態性質，得到盤面傾角37.8◦、盤內徑370-560 au、盤外徑750-1360 au以及位於參考半徑（0."1∼308 au）的盤面旋轉速度8.6 km/s。由此我們計算出系統的動態質量為25.8太陽質量，此數值小於先前Kraus et al. 2017所提出的38太陽質量。新的雙星周盤約束條件及未來雙星系統各個星體的觀測資料將給予我們機會探測IRAS17216-3801可能的形成機制。
