Preliminary Trigonometric Parallaxes of 184 Late-T and Y Dwarfs and an Analysis of the Field Substellar Mass Function into the "Planetary" Mass Regime
J. Davy Kirkpatrick, Emily C. Martin, Richard L. Smart +16
We present preliminary trigonometric parallaxes of 184 late-T and Y dwarfs using observations from Spitzer (143), USNO (18), NTT (14), and UKIRT (9). To complete the 20-pc census o…
Radii of 88 M Subdwarfs and Updated Radius Relations for Low-Metallicity M Dwarf Stars
Aurora Y. Kesseli, J. Davy Kirkpatrick, Sergio B. Fajardo-Acosta +9
M subdwarfs are low-metallicity M dwarfs that typically inhabit the halo population of the Galaxy. Metallicity controls the opacity of stellar atmospheres; in metal poor stars, hyd…
Y dwarf Trigonometric Parallaxes from the Spitzer Space Telescope
Emily C. Martin, J. Davy Kirkpatrick, Charles A. Beichman +12
Y dwarfs provide a unique opportunity to study free-floating objects with masses 30 M and atmospheric temperatures approaching those of known Jupiter-like exoplanets. Ob…
The Science Advantage of a Redder Filter for WFIRST
John Stauffer, George Helou, Robert A. Benjamin +13
WFIRST will be capable of providing Hubble-quality imaging performance over several thousand square degrees of the sky. The wide-area, high spatial resolution survey data from WFIR…
Science Impacts of the SPHEREx All-Sky Optical to Near-Infrared Spectral Survey II: Report of a Community Workshop on the Scientific Synergies Between the SPHEREx Survey and Other Astronomy Observatories
Olivier Doré, Michael W. Werner, Matthew L. N. Ashby +60
SPHEREx is a proposed NASA MIDEX mission selected for Phase A study. SPHEREx would carry out the first all-sky spectral survey in the near infrared. At the end of its two-year miss…
Spitzer Light Curves of the Young, Planetary-Mass TW Hya Members 2MASS J11193254-1137466AB and WISEA J114724.10-204021.3
Adam C. Schneider, Kevin K. Hardegree-Ullman, Michael C. Cushing +2
We present Spitzer Space Telescope time-series photometry at 3.6 and 4.5 m of 2MASS J111932541137466AB and WISEA J114724.10204021.3, two planetary-mass, late-type (L…
