First results from a photometric infrared survey for Vega-like disks around nearby main-sequence stars
We have undertaken a survey for Vega–like disks around nearby main–sequence stars by making photometric measurements with ISOPHOT at four wavelengths between 25 and 180 m. Our goal is to establish how common Vega–like disks are, and how their presence depends on the fundamental properties of main–sequence stars (mass, age, rotation etc.). Here we present first results that concern Vega itself a...
متن کاملNew Debris Disks around Nearby Main-sequence Stars: Impact on the Direct Detection of Planets
Using the MIPS instrument on Spitzer, we have searched for infrared excesses around a sample of 82 stars, mostly F, G, andKmain-sequence field stars, alongwith a small number of nearbyM stars. These stars were selected for their suitability for future observations by a variety of planet-finding techniques. These observations provide information on the asteroidal and cometary material orbiting t...
متن کاملEmpirical Isochrones for Low Mass Stars in Nearby Young Associations
Absolute ages of young stars are important for many issues in pre-main sequence stellar and circumstellar evolution but are long recognized as difficult to derive and calibrate. In this paper, we use literature spectral types and photometry to construct empirical isochrones in HR diagrams for low-mass stars and brown dwarfs in the η Cha, ǫ Cha, and TW Hya Associations and the β Pic and Tuc-Hor ...
متن کاملThe Gaia mission Pulsating stars with Gaia
Gaia is a cornerstone mission of the European Space Agency (ESA) selected in 2000, with a target launch date of 2011. The Gaia mission will perform a survey of about 1 billion sources brighter than V = 20. Its goal is to provide astrometry leading to parallaxes, proper-motions and positions. Astrometric data are complemented by multicolour photometry and a spectroscopic instrument (up to V = 17...
متن کاملRotational Evolution of Solar-Like Stars in Clusters from Pre-Main Sequence to Main Sequence: Empirical Results
Rotation periods are now available for ∼500 pre-main sequence and recently arrived main sequence stars of solar-like mass (0.4-1.2 M⊙) in five nearby young clusters: the Orion Nebula Cluster, NGC 2264, α Per, IC 2602 and the Pleiades. In combination with estimates of stellar radii these data allow us to construct distributions of surface angular momentum per unit mass at three different epochs:...
