Ariel space mission selected stellar calibrators
The ESA space mission Ariel requires bright sources that are stable at the level of 100 ppm over 6 hours in order to accurately measure exoplanet atmospheres through... -
IRS calibration to IRAC: 61 IRS standard stars
We present 3.6 and 4.5{mu}m photometry for a set of 61 standard stars observed by Spitzer's Infrared Spectrograph (IRS). The photometry was obtained with the Infrared Array... -
Infrared absolute calibration. I. Calibration stars
A challenge in absolute calibration is to relate very bright stars with physical flux measurements to faint ones within range of modern instruments, e.g., those on large... -
JMMC Stellar Diameters Catalogue - JSDC. Version 2
This catalogue contains stellar angular diameter estimates for nearly all the stars of the Hipparcos and Tycho catalogue that have an associated spectral type in Simbad/CDS. The... -
UBVRI standard stars in the E-regions
Photometry on the UBVRI Kron-Cousins system is presented for 102 stars covering the magnitude range 7 to 16 in the nine Harvard E-regions. These stars, at declination close to... -
MIPS 24um calibrators
We present the stellar calibrator sample and the conversion from instrumental to physical units for the 24{mu}m channel of the Multiband Imaging Photometer for Spitzer (MIPS).... -
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')... -

Standard errors for PPM and Tycho stars
The connection between the optical reference frame and the radio one constitutes one of the main purposes of the astrometry. The paper is pointing out the contribution of the... -
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 (2016)
We continue the annual publications of the magnetic field measurements of chemically peculiar stars. Observations were carried out with the Main Stellar Spectrograph of the 6-m... -
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... -
Magnetic fields of CP stars (2013)
We present the results of measuring longitudinal magnetic fields (B_e), rotation velocities (v_esini), and radial velocities (RV) of 107 stars observed with the Main Stellar... -
Magnetic fields of CP stars (2014)
We present the results of measuring longitudinal magnetic fields (B_e), and radial velocities (RV) of 74 stars observed with the Main Stellar Spectrograph (MSS) of the 6-m BTA... -
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,...
