The Nearby Spectroscopic Binaries re-visited with Hipparcos (2007)

Jean-Louis Halbwachs, Frederic Arenou

Some results of the Coravel survey of spectroscopic binaries among nearby stars are revised, using additional data coming from the Hipparcos satellite. The high precision Hipparcos parallaxes are...

Seven SB2 masses using Hipparcos intermediate astrometric data (2007)

Frederic Arenou, Jean-louis Halbwachs, Michel Mayor, Julienne Palasi

The spectroscopic orbital elements of seven double-lined spectroscopic binaries have been combined with the Hipparcos astrometric data. Dynamical masses and magnitude differences are determined with...

Astrometric and Light-travel Time Orbits to Detect Low-mass Companions: A Case Study of the Eclipsing System R Canis Majoris (2002)

Ribas, Ignasi, Arenou, Frederic, Guinan, Edward F.

We discuss a method to determine orbital properties and masses of low-mass bodies orbiting eclipsing binaries. The analysis combines long-term eclipse timing modulations (light-travel time or LTT...

Revisiting Hipparcos data for pre-main sequence stars (1999)

Bertout, Claude, Robichon, Noel, Arenou, Frederic

We cross-correlate the Herbig & Bell and Hipparcos Catalogues in order to extract the results for young stellar objects (YSOs). We compare the distances of individual young stars and the distance of...
