Published in 2022 at "New Astronomy"

DOI: 10.1016/j.newast.2021.101708

Abstract: Abstract We present new results of our long-term observational project to analyze the variations of the orbital period for early-type eccentric eclipsing binaries. Altogether 77 new mid-eclipse times were measured or derived for two eclipsing… read more here.

Published in 2018 at "Astronomy and Astrophysics"

DOI: 10.1051/0004-6361/201730655

Abstract: Context. Multiple stellar systems are unique laboratories for astrophysics. Analysis of their orbital dynamics, if well characterized from their observations, may reveal invaluable information about the physical properties of the participating stars. Unfortunately, there are… read more here.

Published in 2023 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stad1291

Abstract: In this paper we study high resolution spectra of 19 stars that have metallicity estimates below –3.5 using at least two metallicity sensitive photometric indices based on Pristine photometry. The purpose is to understand what… read more here.

Published in 2024 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stae1459

Abstract: The discrepancy between the observed and the predicted radii in low-mass stars is a well-known and yet to be resolved problem. Although various theoretical approaches have been developed since the first appearance of the problem,… read more here.
