Twenty-five years of exoplanet discoveries: The exoplanet hosts
Bárbara Rojas-Ayala
For centuries, humanity wondered if there were other worlds like ours in the Universe. For about a quarter of a century, we have known that planetary systems exist around other sta…
Planetesimals Around Stars with TESS (PAST): II. An M Dwarf "Dipper" Star with a Long-Lived Disk in the TESS Continuous Viewing Zone
Eric Gaidos, Andrew W. Mann, Bárbara Rojas-Ayala +6
Studies of T Tauri disks inform planet formation theory; observations of variability due to occultation by circumstellar dust are a useful probe of unresolved, planet-forming inner…
SWEET-Cat 2.0: The Cat just got SWEETer; Higher quality spectra and precise parallaxes from GAIA eDR3
S. G. Sousa, V. Adibekyan, E. Delgado-Mena +13
Aims. The catalog of Stars With ExoplanETs (SWEET-Cat) was originally introduced in 2013. Since then many more exoplanets have been confirmed, increasing significantly the number o…
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…
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…
Catalog for the ESPRESSO blind radial velocity exoplanet survey
S. Hojjatpanah, P. Figueira, N. C. Santos +19
One of the main scientific drivers for ESPRESSO,Échelle SPectrograph, is the detection and characterization of Earth-class exoplanets. With this goal in mind, the ESPRESSO Guarante…
A super-Earth and sub-Neptune transiting the late-type M dwarf LP 791-18
Ian J. M. Crossfield, William Waalkes, Elisabeth R. Newton +57
Planets occur most frequently around cool dwarfs, but only a handful of specific examples are known to orbit the latest-type M stars. Using TESS photometry, we report the discovery…
The Metallicity-Period-Mass Diagram of low-mass exoplanets
S. G. Sousa, V. Adibekyan, N. C. Santos +14
The number of exoplanet detections continues to grow following the development of better instruments and missions. Key steps for the understanding of these worlds comes from their…
A super-Earth and two sub-Neptunes transiting the nearby and quiet M dwarf TOI-270
Maximilian N. Günther, Francisco J. Pozuelos, Jason A. Dittmann +57
We report the Transiting Exoplanet Survey Satellite discovery of three small planets transiting one of the nearest and brightest M dwarf hosts to date, TOI-270 (TIC 259377017; K-ma…
SWEET-Cat updated. New homogenous spectroscopic parameters
S. G. Sousa, V. Adibekyan, E. Delgado-Mena +14
Context: Exoplanets have now been proven to be very common. The number of its detections continues to grow following the development of better instruments and missions. One key ste…
Planet Detectability in the Alpha Centauri System
Lily L. Zhao, Debra A. Fischer, John M. Brewer +2
We use more than a decade of radial velocity measurements for Cen A, B, and Proxima Centauri from HARPS, CHIRON, and UVES to identify the and orbital periods of plan…
The TESS Input Catalog and Candidate Target List
Keivan G. Stassun, Ryan J. Oelkers, Joshua Pepper +17
The Transiting Exoplanet Survey Satellite (TESS) will be conducting a nearly all-sky photometric survey over two years, with a core mission goal to discover small transiting exopla…
Radial velocity information content of M dwarf spectra in the near-infrared
P. Figueira, V. Zh. Adibekyan, M. Oshagh +7
Aims: We evaluate the radial velocity (RV) information content and achievable precision on M0-M9 spectra covering the ZYJHK bands. We do so while considering both a perfect atmosph…
