Rediscussion of eclipsing binaries. Paper 31. The slowly-pulsating B-star system CV Velorum in the PLATO southern field
John Southworth
CV Vel is a detached eclipsing binary containing two B2.5 V stars in a circular orbit of period 6.889 d. Both stars show line-profile variations arising from g-mode oscillations, c…
V446 Cephei: a Cep pulsator in a multiple system
A. Moharana, J. Southworth, K. Pavlovski +7
Cep stars in eclipsing binary (EB) systems give us an opportunity to put observational constraints on their structure and stellar parameters. We present a comprehensive analys…
The PLATO Science Calibration and Validation Plan: Targets for the First Long-pointing Field
Konstanze Zwintz, Conny Aerts, Andrew Tkachenko +56
In order to meet the science goals of the PLATO space mission, an extensive science calibration and validation plan has been designed. This paper describes this plan, as well as th…
Rediscussion of Eclipsing Binaries. Paper XXX. The Slightly Evolved F-type System BK Pegasi
A. C. Kutluay, J. Southworth
BK Peg is a double-lined detached eclipsing binary containing two late-F stars in an orbit with small eccentricity. We use light curves from the Transiting Exoplanet Survey Satelli…
Rediscussion of eclipsing binaries. Paper XXIX. The F-type twin system BS Draconis
John Southworth
We present an analysis of BS Dra, a detached eclipsing binary containing two almost-identical F3 V stars in a 3.36-d circular orbit, based on 40 sectors of observations from the Tr…
The SB9 catalogue: status, comparison with non-single stars from Gaia DR3 and evolution to SBX
T. Merle, A. Jorissen, S. Alexandre +9
The Ninth Catalogue of Spectroscopic Binary Orbits (SB9) is a comprehensive compilation of spectroscopic binaries (SBs) with orbital parameters sourced from literature, comprising…
