Journal ArticleDOI
A Re-appraisal of the Habitability of Planets Around M Dwarf Stars
Jill Tarter,Peter Backus,Rocco L. Mancinelli,Jonathan M. Aurnou,Dana E. Backman,Gibor Basri,Alan P. Boss,Andrew Clarke,Drake Deming,Laurance R. Doyle,Eric D. Feigelson,Friedmann Freund,David Grinspoon,Robert M. Haberle,Steven A. Hauck,Martin J. Heath,Todd J. Henry,Jeffery L. Hollingsworth,Manoj Joshi,Steven Kilston,Michael C. Liu,Eric Meikle,I. Neill Reid,Lynn J. Rothschild,John Scalo,Antígona Segura,Carol M. Tang,James M. Tiedje,Margaret Turnbull,Lucianne M. Walkowicz,Arthur L. Weber,Richard E. Young +31 more
TL;DR: In this paper, the authors re-examined what is known at present about the potential for a terrestrial planet forming within, or migrating into, the classic liquid-surface-water habitable zone close to an M dwarf star.
Journal ArticleDOI
Stellar abundances in the solar neighborhood: the hypatia catalog
Natalie R. Hinkel,Natalie R. Hinkel,Francis Timmes,Francis Timmes,Patrick A. Young,Michael D. Pagano,Margaret Turnbull +6 more
TL;DR: In this article, the authors compile spectroscopic abundance data from 84 literature sources for 50 elements across 3058 stars in the solar neighborhood, within 150 pc of the Sun, to produce the Hypatia catalog.
Journal ArticleDOI
Detectability of Planetary Characteristics in Disk-Averaged Spectra II: Synthetic Spectra and Light-Curves of Earth
Giovanna Tinetti,Victoria S. Meadows,David Crisp,Nancy Y. Kiang,Brian H. Kahn,Emmanuel Bosc,Evan Fishbein,Thangasamy Velusamy,Margaret Turnbull +8 more
TL;DR: Modeling the disk-averaged sensitivity to the "red-edge," a distinctive spectral signature of vegetation, showed that Earth's land vegetation could be seen in disk-aversaged spectra, even with cloud cover, when the signal was averaged over the daily time scale.
Journal ArticleDOI
Detectability of planetary characteristics in disk-averaged spectra. I: The Earth model.
Giovanna Tinetti,Victoria S. Meadows,David Crisp,W. Fong,Evan Fishbein,Margaret Turnbull,Jean-Pierre Bibring +6 more
TL;DR: A spatially and spectrally resolved model of the Earth is developed and comparison between the data and model indicates that several atmospheric species can be identified in disk-averaged Earth spectra, and potentially detected depending on the wavelength range and resolving power of the instrument.
Journal ArticleDOI
Target Selection for SETI. I. A Catalog of Nearby Habitable Stellar Systems
Margaret Turnbull,Jill Tarter +1 more
TL;DR: The catalog of Nearby Habitable Systems (HabCat) was created from the Hipparcos Catalogue by examining the information on distances, stellar variability, multiplicity, kinematics, and spectral classification for the 118,218 stars contained therein this paper.
