Gaia method paper: an algorithm to detect flare events in Gaia time-series
E. Distefano, A. C. Lanzafame, A. F. Lanza +14
The third Gaia data release (GDR3) includes the gdr3_rotmod catalogue of 474026 stars with variability that is attributed to magnetic activity analogous to that observed in the Sun…
Polytropic stellar wind models with strongly localized heating
L. Westrich, B. Shergelashvili, H. Fichtner +1
Polytropic models of stellar winds remain to be useful tools because they allow for a simple description of the energy balance of the expanding plasma without explicitly specifying…
Hydrodynamical models of the Lyr A circumstellar disc
Kristián Vitovský, Miroslav Brož
We study dynamics of circumstellar discs, with a focus on the Lyrae A binary system. This system with ongoing mass transfer has been extensively observed, using photometry, spe…
Study of the Cet Binary with Speckle Interferometric, Photometric and Spectroscopic Techniques
V. V. Dyachenko, I. A. Yakunin, R. M. Bayazitov +8
We present a refined speckle-interferometric orbit of a binary system Cet, with the main component studied based on the analysis of photometric and spectroscopic data, obtained…
The first measurements of carbon isotopic ratios in post-RGB stars: SZ Mon and DF Cyg. E-iSpec: A spectral analysis tool to derive elemental abundances and isotopic ratios for evolved stars
Maksym Mohorian, Devika Kamath, Meghna Menon +4
Dusty post-red giant branch (post-RGB) stars are low- and intermediate-mass stars where the RGB evolution was prematurely terminated by a poorly understood binary interaction. Thes…
VLTI/GRAVITY Observations and Characterization of the Brown Dwarf Companion HD 72946 B
W. O. Balmer, L. Pueyo, T. Stolker +96
Tension remains between the observed and modeled properties of substellar objects, but objects in binary orbits, with known dynamical masses can provide a way forward. HD 72946 B i…
