Silicate Precursor Silane detected in Cold Low-Metallicity Brown Dwarf
Jacqueline K. Faherty, Aaron M. Meisner, Ben Burningham +28
Within 20 pc of the Sun there are currently 29 known cold brown dwarfs, sources with measured distances and an estimated effective temperature between that of Jupiter (170K) and ~5…
Wide-Field InfraRed Survey Telescope (WFIRST) Interim Report
James Green, Paul Schechter, Charles Baltay +19
In December 2010, NASA created a Science Definition Team (SDT) for WFIRST, the Wide Field Infra-Red Survey Telescope, recommended by the Astro 2010 Decadal Survey as the highest pr…
The Disk Gas Mass and the Far-IR Revolution
Edwin A. Bergin, Klaus M. Pontoppidan, Charles M. Bradford +13
The gaseous mass of protoplanetary disks is a fundamental quantity in planet formation. The presence of gas is necessary to assemble planetesimals, it determines timescales of gian…
The Origins Space Telescope
Cara Battersby, Lee Armus, Edwin Bergin +36
The Origins Space Telescope, one of four large Mission Concept studies sponsored by NASA for review in the 2020 US Astrophysics Decadal Survey, will open unprecedented discovery sp…
Super-Eddington Accretion in the WISE-Selected Extremely Luminous Infrared Galaxy W2246-0526
Chao-Wei Tsai, Peter Eisenhardt, Hyunsung Jun +8
We use optical and near-infrared spectroscopy to observe rest-UV emission lines and estimate the black hole mass of WISEA J224607.56-052634.9 (W2246-0526) at z = 4.601, the most lu…
ExoPTF Science Uniquely Enabled by Far-IR Interferometry: Probing the Formation of Planetary Systems, and Finding and Characterizing Exoplanets
David Leisawitz, Tom Armstrong, Chad Bender +28
By providing sensitive sub-arcsecond images and integral field spectroscopy in the 25 - 400 micron wavelength range, a far-IR interferometer will revolutionize our understanding of…
