TOI 122b and TOI 237b, two small warm planets orbiting inactive M dwarfs, found by \textit{TESS}
William C. Waalkes, Zachory K. Berta-Thompson, Karen A. Collins +39
We report the discovery and validation of TOI 122b and TOI 237b, two warm planets transiting inactive M dwarfs observed by \textit{TESS}. Our analysis shows TOI 122b has a radius o…
TOI 540 b: A Planet Smaller than Earth Orbiting a Nearby Rapidly Rotating Low-mass Star
Kristo Ment, Jonathan Irwin, David Charbonneau +20
We present the discovery of TOI 540 b, a hot planet slightly smaller than Earth orbiting the low-mass star 2MASS J05051443-4756154. The planet has an orbital period of $P = 1.23914…
LHS 1815b: The First Thick-Disk Planet Detected By TESS
Tianjun Gan, Avi Shporer, John H. Livingston +35
We report the first discovery of a thick-disk planet, LHS 1815b (TOI-704b, TIC 260004324), detected in the TESS survey. LHS 1815b transits a bright (V = 12.19 mag, K = 7.99 mag) an…
Stellar Characterization of M-dwarfs from the APOGEE Survey: A Calibrator Sample for the M-dwarf Metallicities
Diogo Souto, Katia Cunha, Verne V. Smith +18
We present spectroscopic determinations of the effective temperatures, surface gravities and metallicities for 21 M-dwarfs observed at high-resolution (R 22,500) in the \tex…
Derivation of parameters for 3748 FGK stars using H-band spectra from APOGEE Data Release 14
Pedro Sarmento, Elisa Delgado Mena, Bárbara Rojas-Ayala +1
The Apache Point Observatory Galactic Evolution Experiment (APOGEE) has observed the H-band spectra of over 200 000 stars with . The main motivation for this work is t…
The First Habitable Zone Earth-sized Planet from TESS. I: Validation of the TOI-700 System
Emily A. Gilbert, Thomas Barclay, Joshua E. Schlieder +92
We present the discovery and validation of a three-planet system orbiting the nearby (31.1 pc) M2 dwarf star TOI-700 (TIC 150428135). TOI-700 lies in the TESS continuous viewing zo…
