Evolutionary Sequences
The tracks cover the mass interval from 0.6 to 120M_{sun}_, for 7 different metallicities The isochrones are derived from the evolutionary tracks listed in the item above. -
Geneva stellar evolution tracks and isochrones
This database was created from an updated version of the empirically and semi-empirically calibrated BaSeL library of synthetic stellar spectra of Lejeune et al. (1997, Cat. ,... -
A planetary-mass companion to a solar-type star
The Young Suns Exoplanet Survey (YSES) consists of a homogeneous sample of 70 young, solar-mass stars located in the Lower Centaurus-Crux subgroup of the Scorpius-Centaurus... -
UVIT-HST-GAIA view of NGC 288 hot stars
A complete census of the blue horizontal branch (BHB) and blue straggler star (BSS) population within a 10' radius from the centre of the globular cluster NGC 288 is presented,... -
The Gaia 20 pc white dwarf sample
Using Gaia DR2 data, we present an up-to-date sample of white dwarfs within 20pc of the Sun. In total we identified 139 systems in Gaia DR2, nine of which are new detections,... -
UBVI CCD Photometry of M11 - II.
This directory contains Johnson-Cousins UBVI photometric data for M11 (NGC 6705) and a neighboring field (around PN G027.4-03.5). The photometric data for M11 are tightly... -
Stellar composition of CMa R1
This directory contains movies in mpeg format which show models for the time evolution of the Hertzsprung-Russell diagram of a very young open cluster between 0 and 30Myr. Four... -
Data and parameters for subgiant sample
Given their location on the Hertzsprung-Russell (H-R) diagram, thoroughly characterized subgiant stars can place stringent constraints on a wide range of astrophysical problems.... -
VI photometry of sources in the halo of NGC253
We have obtained Magellan/IMACS and HST/ACS imaging data that resolve red giant branch stars in the stellar halo of the starburst galaxy NGC 253. The HST data cover a small... -
Optical photometry of the ONC. II.
We present a new analysis of the stellar population of the Orion Nebula Cluster (ONC) based on multi-band optical photometry and spectroscopy. We study the color-color diagrams... -
HST observations of old clusters in the LMC
We present V, V-I color-magnitude diagrams (CMDs) for three old star clusters in the Large Magellanic Cloud (LMC): NGC 1466, NGC 2257, and Hodge 11. Our data extend {~}3 mag... -
Teff, B-V and BC relation
The table provides improved numerical relations between effective temperatures of stars, their B-V colors, and their bolometric corrections (BC) for the purpose of comparing... -
Stromgren photometry of IC 4651
CCD photometry of the intermediate-age open cluster IC 4651 on the uvbyH{beta} system is presented and analyzed. By using a combination of the information from the... -
JK Photometry of globular clusters M15 & M56
Infrared JKs-band photometry of the Galactic globular clusters M15 and, for the first time, M56 is presented. We estimate the reddening [E(B-V) = 0.18 {=/-} 0.08 mag] and... -
WFPC 2 imaging of young LMC clusters
We have carried out Wide Field Planetary Camera 2 (WFPC2) F160BW, F555W, and F656N imaging of four young populous clusters: NGC 330, in the Small Magellanic Cloud, and NGC 1818,... -
Ages for globular clusters in the halo
We have used the Wide Field Planetary Camera 2 on the Hubble Space Telescope to obtain photometry of the outer halo globular clusters Palomar 3, Palomar 4, and Eridanus. These... -
HST color-magnitude diagrams of the LMC
We present results on the analysis of background field stars found in Hubble Space Telescope Wide Field Planetary Camera 2 observations of six of the old globular clusters of... -
Grids of stellar models. VIII.
We present stellar evolutionary models covering the mass range from 0.4 to 1M_{sun} calculated for metallicities Z=0.020 and 0.001 with the MHD equation of state (Hummer &... -
NGC 6611 compiled catalog
This catalogue contains data on stars in sky area of the open cluster NGC 6611. The catalogue is based on a new reduction of positions, proper motions, and photometric data... -
Grids of stellar models. VII.
We present a new grid of stellar models from 0.8 to 60M_{sun} at Z=0.10, with mass loss and moderate overshooting, from the zero age main sequence to either the helium flash...
