Secondary velocity standards at NGP
We present mean radial velocities for 143 stars in Selected Area 57 at the north Galactic pole that are suitable for use as secondary velocity standards. The stars were drawn... -
BVI photometry in NGC 300
Based on 13 nights of observations of four fields in NGC 300, we have set up an extensive sequence of stars with accurate BVI photometry covering a relatively large (25'x25')... -
APOGEE DR17 standard stars radial velocities
We present an updated catalog of 46753 radial velocity (RV) standard stars selected from the APOGEE DR17. These stars cover the Northern and Southern Hemispheres almost evenly,... -
UBVRI phot. for galaxies, Gal. GCs & stars
From 1982 January to 1988 October, I used the 76-cm and 91-cm (30-inch and 36-inch) reflectors at McDonald Observatory in West Texas for UBV(RI)c observations of 239 galaxies,... -
Catalog of magnetic CP stars (2015)
The paper presents magnetic field measurements and physical parameters for 96 stars. Observations were carried out in 2015 with the 6-m BTA telescope using the Main Stellar... -
Ori OB1 CP stars magnetic fields. V.
The paper presents magnetic field measurements for 15 chemically peculiar (CP) stars of subgroup 1b in the Orion OB1 association. We have found that the proportion of stars with... -
Ori OB1 CP stars magnetic fields. V.
The paper presents the results of magnetic field measurements of 27 chemically peculiar stars in subgroups (c) and (d) of the Orion OB1 association. In total, more than 140... -
Magnetic fields of CP stars (2012)
We present the results of measuring longitudinal magnetic fields (Be), rotation velocities (v_esini), and radial velocities (VR) of 163 stars observed with the Main Stellar... -
Ori OB1 CP stars magnetic fields. III.
The paper presents results of magnetic field measurements of 10 chemically peculiar stars of subgroup (a) in the Orion OB1 association: HD33917, HD34859, HD35008, HD35039,... -
CP stars magnetic fields catalog (2009)
We present the results of measuring longitudinal magnetic fields (B_e), rotation velocities (v_e_sini), and radial velocities (V_r_) of 44 stars observed with the Main Stellar... -
High polarization standard observations
Observations of polarization position angle ({theta}) standards made from 2014 to 2023 with the High Precision Polarimetric Instrument (HIPPI) and other HIPPI-class polarimeters... -
Analysis of Gaia RV standards
Our main aim is to test the non-variability of the radial velocity (RV) of a sample of 2351 standard stars used for wavelength calibration of the Radial Velocity Spectrometer... -
MW field and cluster RR Lyrae stars
We present new luminosity-metallicity (LZ ; M_V_-[Fe/H] and M_G_-[Fe/H]) and relations and, for the first time, empirical, Gaia three-band (G, G_BP_, G_RP_)... -
NIR light curves study of DCEPs in the LMC
We employed the VISTA near-infrared YJKs survey of the Magellanic System (VMC) to analyse the Y, J, K_s_ light curves of {delta} Cepheid stars (DCEPs) in the Large Magellanic... -
RR Lyrae study with ZTF DR3 light curves
We present an RR Lyrae (RRL) catalogue based on the combination of the third data release of the Zwicky Transient Facility (ZTF DR3) and Gaia EDR3. We use a multistep... -
Improved and new RVs for the GALAH+ survey
GALAH+ is a magnitude-limited survey of high-resolution stellar spectra obtained by the HERMES spectrograph at the Australian Astronomical Observatory. Its third data release... -
Asteroseismic study of TESS mission's DSCTs
We investigate the relationship between the asteroseismic indices and the physical quantities of 438 {delta} Scuti (DSCT) stars observed by the Transiting Exoplanet Survey... -
Study of Cepheids in open clusters
In this paper, we revisit the problem of identifying bona fide cluster Cepheids by performing an all-sky search for Cepheids associated with open clusters and making use of... -
Gaia Spectrophotometric Standard Stars. V.
We present the flux tables of the spectrophotometric standard stars (SPSS) used to calibrate in flux the Gaia DR2 and (E)DR3 data releases. The latest SPSS grid version contains... -
UVIT and GALEX count rates
We have studied the performance of the Ultraviolet Imaging Telescope payload on AstroSat and derived a calibration of the far-ultraviolet (FUV) and near-ultraviolet (NUV)...
