The K2 and TESS Synergy. II. Revisiting 26 Systems in the TESS Primary Mission

The Astronomical Journal, 2023
The legacy of NASA’s K2 mission has provided hundreds of transiting exoplanets that can be revisited by new and future facilities for further characterization, with a particular focus on studying the atmospheres of these systems. However, the majority of

Catalog of New K2 Exoplanet Candidates from Citizen Scientists [PDF]

Research Notes of the AAS, 2019
We provide 28 new planet candidates that have been vetted by citizen scientists and expert astronomers. This catalog contains 9 likely rocky candidates ($R_{pl} < 2.0R_\oplus$) and 19 gaseous candidates ($R_{pl} > 2.0R_\oplus$). Within this list we find one multi-planet system (EPIC 246042088).

Catalog for the ESPRESSO blind radial velocity exoplanet survey [PDF]

Astronomy & Astrophysics, 2019
Aims.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 guaranteed time observations (GTO) Catalog identifies the best target stars for a blind search for the radial velocity (RV) signals caused by Earth-class exoplanets.Methods ...

Gaia search for stellar companions of TESS Objects of Interest IV

Astronomische Nachrichten, Volume 344, Issue 7, September 2023., 2023
We present the latest results of our ongoing multiplicity study of (Community) TESS Objects of Interest, using astrometric and photometric data from the ESA‐Gaia mission to detect stellar companions of these stars and characterize their properties. A total of 134 binary, 6 hierarchical triple, and two quadruple star systems are identified among 1106 ...

Multiplicity Boost of Transit Signal Classifiers: Validation of 69 New Exoplanets using the Multiplicity Boost of ExoMiner

The Astronomical Journal, 2023
Most existing exoplanets are discovered using validation techniques rather than being confirmed by complementary observations. These techniques generate a score that is typically the probability of the transit signal being an exoplanet ( y ( x ...
