RVs of TIC 56913729 & TIC 97729372 from LAMOST DR10
Utilizing data from the Transiting Exoplanet Survey Satellite (TESS) and LAMOST, we present a photometric and spectroscopic investigation of two new K-type low-mass eclipsing... -
Limb-darkening coefficients for JWST
Modeling observations of transiting exoplanets or close binary systems by comparing the observations with theoretical light curves requires precise knowledge of the distribution... -
Photometric observations of GOTO065054+593624
Dwarf novae are astrophysical laboratories for probing the nature of accretion, binary mass transfer, and binary evolution -- yet their diverse observational characteristics... -
Gaia DR3 WD-MS parameters
Binary stars containing a white dwarf and a main-sequence star, WDMS binaries, can be used to study a wide range of aspects of stellar astrophysics. We build a magnitude-limited... -
Corot photometry of TYC 455-791-1
We report the discovery and analysis of very narrow transits in the eccentric spectroscopic binary TYC 455-791-1=HSS 348 (IC 4756). We obtained high-precision CoRoT photometry... -
Variability survey of brightest stars
The stellar evolution theory of massive stars remains uncalibrated with high-precision photometric observational data mainly due to small number of luminous stars monitored from... -
10 very-low-mass stars photometry
Measurements of the physical properties of stars at the lower end of the main sequence are scarce. In this context we report masses, radii and surface gravities of ten... -
Rotation periods and catalogue information
We analysed space photometry from the TESS mission for a sample of 1002 mCP stars discovered in LAMOST archival spectra. Of the 782 mCP stars with available TESS data, rotation... -
Ji photometry of WTS 19g-4-02069
Star formation theory predicts that short-period M-dwarf binaries with highly unequal-mass components are rare. First, the mass ratio of close binary systems is driven to unity... -
Light-curve and radial velocities of BD+42 2782
BD+42 2782 was recently discovered to be a variable star with a W UMa-type, eclipsing-binary light curve. We have obtained the first photoelectric light curves (R_C_, I_C_) and... -
BVRI light curves of Westerlund 1 stars
This paper presents the first optical variability study of the Westerlund 1 super star cluster in search of massive eclipsing binary systems. A total of 129 new variable stars... -
Velocity and H{alpha} width of 22 Vul
The 22 Vul system is important for studying the winds and chromospheres of cool evolved stars because the G4 I component is rotating rapidly and probably faster than... -
BV photometry of V532 Mon
The first two sets of complete charge-coupled device light curves in the B and V bands of the short-period binary system, V532 Mon, are presented. The light curves are analyzed... -
Transits observed in OGLE 2001-2003
We present results of an extensive photometric search for planetary and low-luminosity object transits in the Galactic disk stars commencing the third phase of the Optical... -

Vilnius Photometry of HD211853
New photometric observations of the Wolf-Rayet binary HD 211853 are presented. They were obtained with the 1-m reflector of the Institute of Theretical Physics and Astrophysics... -
