Validating AU Microscopii d with Transit Timing Variations
Justin M. Wittrock, Peter Plavchan, Bryson L. Cale +31
AU Mic is a young (22 Myr) nearby exoplanetary system that exhibits excess TTVs that cannot be accounted for by the two known transiting planets nor stellar activity. We present th…
Characterizing and Mitigating the Impact of Telluric Absorption in Precise Radial Velocities
Sharon Xuesong Wang, Natasha Latouf, Peter Plavchan +7
Precise radial velocity (PRV) surveys are important for the search of Earth analogs around nearby bright stars. Such planets induce a small stellar reflex motion with RV amplitude…
A close-in puffy Neptune with hidden friends: The enigma of TOI 620
Michael A. Reefe, Rafael Luque, Eric Gaidos +82
We present the validation of a transiting low-density exoplanet orbiting the M2.5 dwarf TOI 620 discovered by the NASA TESS mission. We utilize photometric data from both TESS and…
Transit timing variations of AU Microscopii b and c
Gy. M. Szabó, Z. Garai, A. Brandeker +76
Here we report large-amplitude transit timing variations (TTVs) for AU\,Microcopii b and c as detected in combined TESS (2018, 2020) and CHEOPS (2020, 2021) transit observations. A…
TOI 560 : Two Transiting Planets Orbiting a K Dwarf Validated with iSHELL, PFS and HIRES RVs
Mohammed El Mufti, Peter P. Plavchan, Howard Isaacson +92
We validate the presence of a two-planet system orbiting the 0.15--1.4 Gyr K4 dwarf TOI 560 (HD 73583). The system consists of an inner moderately eccentric transiting mini-Neptune…
Diving Beneath the Sea of Stellar Activity: Chromatic Radial Velocities of the Young AU Mic Planetary System
Bryson Cale, Michael Reefe, Peter Plavchan +52
We present updated radial-velocity (RV) analyses of the AU Mic system. AU Mic is a young (22 Myr) early M dwarf known to host two transiting planets - days, $R_{b}=…
Flares, Rotation, and Planets of the AU Mic System from TESS Observations
Emily A. Gilbert, Thomas Barclay, Elisa V. Quintana +20
AU Mic is a young (24 Myr), pre-Main Sequence M~dwarf star that was observed in the first month of science observations of the Transiting Exoplanet Survey Satellite (TESS) an…
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…
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…
A planet within the debris disk around the pre-main-sequence star AU Microscopii
Peter Plavchan, Thomas Barclay, Jonathan Gagné +84
AU Microscopii (AU Mic) is the second closest pre main sequence star, at a distance of 9.79 parsecs and with an age of 22 million years. AU Mic possesses a relatively rare and spat…
A Hot Saturn Orbiting An Oscillating Late Subgiant Discovered by TESS
Daniel Huber, William J. Chaplin, Ashley Chontos +139
We present the discovery of TOI-197.01, the first transiting planet identified by the Transiting Exoplanet Survey Satellite (TESS) for which asteroseismology of the host star is po…
The Origins Space Telescope: Towards An Understanding of Temperate Planetary Atmospheres
Jonathan Fortney, Tiffany Kataria, Kevin Stevenson +46
The Origins Space Telescope (OST) is one of four mission concepts currently being studied by NASA in preparation for the Astrophysics 2020 Decadal Survey. With active cooling (~4 K…
Life Beyond the Solar System: Remotely Detectable Biosignatures
Shawn Domagal-Goldman, Nancy Y. Kiang, Niki Parenteau +38
For the first time in human history, we will soon be able to apply the scientific method to the question "Are We Alone?" The rapid advance of exoplanet discovery, planetary systems…
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…
Habitability of Planets Orbiting Cool Stars
Rory Barnes, Victoria S. Meadows, Shawn D. Domagal-Goldman +6
Terrestrial planets are more likely to be detected if they orbit M dwarfs due to the favorable planet/star size and mass ratios. However, M dwarf habitable zones are significantly…
