Welcome to the Variable Star One-shot Project
An international collaboration on Variable Stars

The goal of VSOP is to collect, organize, publish and make available to astronomers, publication-quality 1-D calibrated spectra of all unstudied variable stars in both hemispheres, using leading observatories over the world. This wiki-wiki website is used by the worldwide VSOP team to provide a simple and organised access to the data and VSOP results.

If you use VSOP data/or results, you must acknowledge VSOP. See simple instructions.



Latest News: (2007-11-20) Work is being finalized on P77 observations. See Pages Health. A definite procedure will be put in place for binary status.
VSOP Paper One Accepted : Dall et al. 2007, A&A, 470, 1201 (ADS - pdf).
Access to all stars observed with the left-hand menu, or enter a star name in the search box (the wiki resolves star aliases).
Stars have been organized with Categories: HARPS and, FEROS targets, Binaries!, B, A, F, G and K-type stars...
Check out our Scientific Highlights below, or Highlights from P77.
To learn more about the goals of VSOP and its worlwide team, find out here!
As a simple visitor, you cannot modify pages, bu you can always ask the VSOP team to do so.
For any suggestion, problems, with the wiki, contact the wikisysops: Cédric and/or Éric.

VSOP observations with HARPS revealed that NR Peg is a G-type+G-type SB2, with interesting P Cygni profile in Halpha. It also shows an unusual HeI 5875 line. See also other Highlights from P77.

VSOP observations with HARPS revealed that V491 Car is actually a visual binary, composed of a faint star and a bright component that appeared to contains actually two SB2s! The two binaries have similar RVs, and are thus possibly forming a binary+binary system. See also other Highlights from P77.
