TOI-431/HIP 26013: a super-Earth and a sub-Neptune transiting a bright, early K dwarf, with a third RV planet
Ares Osborn, David J. Armstrong, Bryson Cale +125
We present the bright (V), multi-planet system TOI-431, characterised with photometry and radial velocities. We estimate the stellar rotation period to be $30.5 \pm…
Spatially Resolved Observations of the Galactic Center Source, IRS 21
A. Tanner, A. M. Ghez, M. Morris +5
We present diffraction-limited 2-25 micron images obtained with the W. M. Keck 10-m telescopes that spatially resolve the cool source, IRS 21, one of a small group of enigmatic obj…
The Accelerations of Stars Orbiting the Milky Way's Central Black Hole
A. Ghez, M. Morris, E. E. Becklin +2
Recent measurements, of the velocities of stars near the center of the Milky Way have provided the strongest evidence for the presence of a supermassive black hole in a galaxy, but…
The CARMENES search for exoplanets around M dwarfs -- LP 714-47b (TOI 442.01): Populating the Neptune desert
S. Dreizler, I., J. +134
We report the discovery of a Neptune-like planet (LP 714-47 b, P = 4.05204 d, m_b = 30.8 +/- 1.5 M_earth , R_b = 4.7 +/- 0.3 R_earth ) located in the 'hot Neptune desert'. Confirma…
Stellar Orbits Around the Galactic Center Black Hole
A. M. Ghez, S. Salim, S. D. Hornstein +5
We present new proper motion measurements and simultaneous orbital solutions for three newly identified (S0-16, S0-19, and S0-20) and four previously known (S0-1, S0-2, S0-4, and S…
NIRSPEC Radial Velocity Measurements of Late-M Dwarfs
A. Tanner, R. White, J. Bailey +1
With an emphasis in detecting Earth-like planets set forth by the 2010 Decadal Survey and in searching for planets around M dwarfs set forth by the 2008 Exoplanet Task Force, radia…
