Search for planets around stars with wide brown dwarfs
J. Šubjak, N. Lodieu, P. Kabáth +6
Aims. The project aims to understand better the role of wide brown dwarf companions on planetary systems. Methods. We obtained high-resolution spectra of six bright stars with co-m…
Radial velocity confirmation of a hot super-Neptune discovered by TESS with a warm Saturn-mass companion
E. Knudstrup, D. Gandolfi, G. Nowak +59
We report the discovery and confirmation of the planetary system TOI-1288. This late G dwarf harbours two planets: TOI-1288 b and TOI-1288 c. We combine TESS space-borne and ground…
Observations and modeling of spectral line asymmetries in stellar flares
Jiří Wollmann, Petr Heinzel, Petr Kabáth
Stellar flares are energetic events occurring in stellar atmospheres. They have been observed on various stars using photometric light curves and spectra. On some cool stars, flare…
HD 20329b: An ultra-short-period planet around a solar-type star found by TESS
F. Murgas, G. Nowak, T. Masseron +45
We used TESS light curves and HARPS-N spectrograph radial velocity measurements to establish the physical properties of the transiting exoplanet candidate found around the star HD…
HD 191939 revisited: New and refined planet mass determinations, and a new planet in the habitable zone
J. Orell-Miquel, G. Nowak, F. Murgas +20
HD 191939 (TOI-1339) is a nearby (d=54pc), bright (V=9mag), and inactive Sun-like star (G9 V) known to host a multi-planet transiting system. Ground-based spectroscopic observation…
Companions to Kepler giant stars: A long-period eccentric substellar companion to KIC 3526061 and a stellar companion to HD 187878
Marie Karjalainen, Raine Karjalainen, Artie P. Hatzes +12
Context. Our knowledge of populations and occurrence of planets orbiting evolved intermediate-mass stars is still incomplete. In 2010 we started a planet-search program among 95 gi…
