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.

Dust Around Young Stellar Objects

1996
In this paper, the properties of circumstellar dust grains located in the environment of young stellar objects will be reviewed. After a short introduction to the field of young stellar objects, the main results of infrared spectroscopy will be discussed. Infrared and millimetre continuum observations form a further topic of this paper.

Evolution of Young Stellar Objects

2012
This chapter decribes the evolution of stellar objects after the PMF phase when a young stellar object forms via accretion from its circumstellar cloud. It is difficult, if not impossible, to draw a line between the process of protostellar formation and the evolution of a protostar toward a mature star on the main sequence.

Young stellar objects in groups.

1994
The authors present four groups which contain several massive young objects in different evolutionary states, mainly Herbig Ae/Be stars and compact H II regions. They try to ascertain the exact nature of the components of the group, via photometry and spectroscopy. This study is illustrated by the case of AFGL 4029.

Infrared spectra of young stellar objects

2008
We present models of the spectral energy distributions for an evolutionary sequence of young stellar objects, from protostars to pre-main-sequence stars. The protostellar theory, characterized by a central star and disk embedded within an infalling envelope of dust and gas, can explain the observed infrared spectra of embedded IRAS sources associated ...

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.
