ISOPHOT Observations of Vega and Vega-Like Starshigh resolution 60.m scan data to compare with 60.m and 90.m oversampled maps. The dust disk around Vega is clearly resolved. In addition similar maps of HD98800, SAO226057, SAO186777 and α Piscis ustrinus (HR8728) are evaluated, resolving the disks of two Vega-like stars/candidates and providing upper limits for the size of the other two.

We now believe that we understand the phases a dense interstellar cloud passes through in the process of becoming a young star, and we have observational examp

The future of flash in the mobile world, but it no longer occurs inside a star-forming region, so that it can be considered a transition object between the youngest, embedded, stars and main-sequence objects such as Beta Pic, a phase in which the radiation which characterizes the circumstellar dust disk diminishes.

A significant fraction of the much older main-sequence B and A-type stars also shows excess emission at λ ≥ 25µm (the so-called Vega-phenomenon, Backman an
