Infrared Classification of Young Stellar Objects

1996
The radiative transfer equation for a dusty envelope as close as possible to an embedded central source possesses scaling properties. For a given dust chemical composition, the solution depends only on overall optical depth and the functional form of the radial dust distribution.

Chemistry in the Winds of Young Stellar Objects

1998
Abstract The realization that powerful winds accompany the formation of stars has played an important role in understanding how stars form (e.g. Shu, Adams and Lizano 1987; Lada and Shu 1990). Although considerable evidence for mass loss from young stellar objects (YSOs) existed before 1980, the discovery of bipolar molecular outflows

Magnetic fields in young stellar objects

2014 XXXIth URSI General Assembly and Scientific Symposium (URSI GASS), 2014
The formation of stars and planets is accompanied not only by inflows of matter, as one might expect, but also by outflows. These outflows take the form of supersonic and highly collimated jets that can stretch for several light years and extend even beyond the parent molecular cloud.

Detection of young stellar objects with ISO

1997
Preliminary 15μm results obtained with ISOCAM are compared with deep K-band and H_2_O maser observations of a 0.244deg^2^ field in the galactic plane at I=+45^o^. A new maser source is found to be associated with the infrared source with the largest colour index, (m_K_-m_15μm_)>=10, most probably a young star in its earliest evolutionary phase ...

The quest for evolutionarydiagrams of young stellar objects

2007
Young stellar objects (YSOs) are reviewed with an emphasis on their global evolutionary properties. The main classification schemes of YSOs based on the observed continuum spectral energy distributions and the recent suggestion of using a bolometric temperature to characterize the evolutionary status of all YSOs will be first discussed.
