Young stellar objects: the source of gas emission around Herbig Ae/Be stars

PRESS RELEASE Date Released: Friday, October 10, 2008 Source: Astronomy & Astrophysics Based on the articles: "Spatially resolving the hot CO around the young Be star 51 Ophiuchi", by E. Tatulli et al. Original A&A article and "The origin of hydrogen line emission for five Herbig Ae/Be stars spatially resolved by VLTI/AMBER spectro-interferometry", by S. Kraus et al. Original A&A article Published in Astronomy & Astrophysics , 2008, vol. 489-3, pp. 1151-1173 This week, Astronomy & Astrophysics is publishing new high-resolution observations of the gas component surrounding six young stars with the AMBER/VLTI instrument (ESO, Chile). Astronomers were able to measure the spatial distribution of the hydrogen and CO gas emission in the inner disks around six Herbig Ae/Be stars. They found that the gas emission can clearly trace...
