Otero, Sebastian Alberto

Long term variation in Hipparcos data. Also eclipses with elements BJD 2459897.93 + 2.868 d x E, duration 14% and amplitude 0.0005 in TESS data, that may come from a fainter object blended. Exoplanet host candidate with P= 128.2 d in 2025AJ....169...83B but the RV variations (with main P= 130.6 and 66 d) are attributed to rotation (or less likely g-mode non-radial pulsations) in 2025ApJ...985..176B. |
