50 Dra: Am-type twins with additional variability in a non-eclipsing system
M. Skarka, J. Lipták, E. Niemczura +5
The interplay between radiative diffusion, rotation, convection, and magnetism in metallic-line chemically peculiar stars is still not fully understood. Recently, evidence has emer…
TOI-4504: Exceptionally large Transit Timing Variations induced by two resonant warm gas giants in a three planet system
Michaela Vítková, Rafael Brahm, Trifon Trifonov +24
We present a joint analysis of TTVs and Doppler data for the transiting exoplanet system TOI-4504. TOI-4504 c is a warm Jupiter-mass planet that exhibits the largest known transit…
Five new eclipsing binaries with low-mass companions
J. Lipták, M. Skarka, E. Guenther +18
Precise space-based photometry from the Transiting Exoplanet Survey Satellite results in a huge number of exoplanetary candidates. However, the masses of these objects are unknown…
Chemically peculiar stars on the pre-main sequence
L. Kueß, E. Paunzen, N. Faltová +12
Context. The chemically peculiar (CP) stars of the upper main sequence are defined by spectral peculiarities that indicate unusual elemental abundance patterns in the presence of d…
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…
