A Catalog of Homogeneously Derived Stellar Parameters for Spectroscopic Survey Stars

Stefan Y. Stefanov, Evelina Zaharieva, Djemma Ruseva +9

Uniformly derived stellar parameters are vital for exoplanet demographic studies because they directly influence the inferred planetary masses, radii, and bulk densities. This stud…

Long-period magnetic activity in the K dwarf GJ 1137 and a new super-Earth on a 9-day orbit

Denitza Stoeva, Atanas K. Stefanov, Stefan Y. Stefanov +12

Aims: We investigate long-term radial velocity (RV) variability in the K-dwarf star GJ 1137 (HD 93083, HIP52521), a known Saturn-mass exoplanet host, and assess the role of stellar…
