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…
Spin states of X-complex asteroids in the inner main belt -- I. Investigating the Athor and Zita collisional families
D. Athanasopoulos, J. Hanuš, C. Avdellidou +14
The aim of our study is to characterise the spin states of the members of the Athor and Zita collisional families and test whether these members have a spin distribution consistent…
