This data set consists of evolutionary sequences from the Zero Age Horizontal Branch (ZAHB) to the point where log L/Lsun reaches 2.25 on the lower AGB. These calculations have...

The catalog results from a survey for distant Field K giants in the Galactic halo made for purposes of locating a chemically and kinematically unbiased sample out to about 25...

Relative proper motions were determined for 1068 stars with limiting magnitude b=16.5 and located within an area 130'*130' centered at alpha=8h 47.7m,delta=+12 deg.00' and...

This document describes the magnetic tape version of a catalog of 1440 O-B5 star with radial velocities accurate to within 5 km/sec, located within 3 kpc of the sun and within...

Proper motions were determined for 2169 stars with limiting magnitude B = 16.5 mag and located within a 60x60' area centered at RA = 23h54.2min, Dec = 60deg57arcmin (1950.0)....

Proper motions with an 80 year baseline have been determined relative to reference stars with B=13.9mag. determined for 3086 stars brighter than B=15.5mag. within an area of 50'...

A catalog of more than 300 late type stars which display maser line radio emission in OH, H2O or SiO molecules has been compiled. About two thirds of the objects have been...

The INT Galactic Plane Survey (IGAPS) is the merger of the optical photometric surveys, IPHAS and UVEX, based on data from the Isaac Newton Telescope (INT) obtained between 2003...

The mass of a star at formation determines its subsequent evolution and demise. Low-mass stars are the most common products of star formation and their long main-sequence...

The dataset lists all the confirmed globular clusters (GC), all the known candidates GCs, and also all the objects that were identified as candidate GCs in the past and were...

We present a public archive of light-motion curves in Sloan Digital Sky Survey (SDSS) Stripe 82, covering 99{deg} in right ascension (20.7h to 3.3h) and spanning 2.52{deg} in...

The Extended Hipparcos Compilation (XHIP) cross-references the New Hipparcos Reduction (HIP2, Cat. I/311) with relatable data from a broad survey of presently available sources....

We have created specialized target lists for radial velocity surveys that are biased toward stars that (1) possess planets and (2) are easiest to observe with current detection...

Ages, chemical compositions, velocity vectors, and Galactic orbits for stars in the solar neighbourhood are fundamental test data for models of Galactic evolution. The...

The results of BVRI photometric and spectroscopic observations of symbiotic Nova HM Sagittae were made in 1986-2002.

In 1999-2002 the BVRI photometric and spectroscopic observations of FG Sge were made. The star has been in a new R CrB photometric phase since 1992.

UBVR photometric and spectroscopic observations of V838 Mon during the outbursts.

The method of statistical parallaxes is applied to a sample of 262 Rrab RR Lyr type variables with published photoelectric photometry, radial velocities, abundances and with...

Based on high-dispersion echelle spectra taken with the 6-m telescope, detailed chemical composition of the IR source IRAS 20004+2955 identified with the variable star V1027 Cyg...

Kinematic data of 117 open clusters younger than 100 million years with proper motions reduced to the HIPPARCOS reference system are presented. Cone search capability for table...
