ABSTRACT Transiting Exoplanet Survey Satellite (TESS) has produced long-term photometry for millions of stars across the sky. In this work, we present an asteroseismic catalogue of 19 151 red giants in the TESS Continuous Viewing Zones using sectors 1–87 (Years 1–7). We …

Context. HD 140283 is a well-studied metal-poor subgiant and a Gaia benchmark star, often used for testing stellar models due to its proximity, brightness, and low metallicity ([Fe/H]= − 2.3 dex). Aims. Here we present the first asteroseismic analysis of HD 140283, …

We report the discovery of a warm sub-Saturn, TOI-257b (HD 19916b), based on data from NASA's Transiting Exoplanet Survey Satellite (TESS). The transit signal was detected by TESS and confirmed to be of planetary origin based on radial velocity observations. An analysis …

We present the bright (Vmag = 9.12), multiplanet system TOI-431, characterized with photometry and radial velocities (RVs). We estimate the stellar rotation period to be 30.5 ± 0.7 d using archival photometry and RVs. Transiting Exoplanet Survey Satellite (TESS) objects of Interest …
