On presente des cartes de haute resolution (7'') du gaz moleculaire et de l'emission continue dans les noyaux de NGC 2071, W 49 et NGC 7538. Les masses du gaz de haute vitesse, detecte par l'interferometre, sont respectivement de 0,2; 138 et 12 M ○. . L'emission continue a 2,7 mm a ete detectee dans toutes les sourcesread more

Massive Stars : Their Environment and Formation
Guido Garay,Susana Lizano +1 more
TL;DR: In this paper, the physical characteristics of the environment around recently formed massive stars are reviewed and a large body of data, gathered during the last decade, has allowed signi cant progress in the understanding of the physical processes that take place during the formation and early evolution of massive stars.

A HIGH-RESOLUTION STUDY OF GAS AND DUST AROUND YOUNG INTERMEDIATE-MASS STARS: EVIDENCE FOR CIRCUMSTELLAR DISKS IN HERBIG Ae SYSTEMS
TL;DR: In this paper, the environments of seven pre-main-sequence stars of spectral type Ae using millimeter-wave continuum and molecular line aperture synthesis imaging were probed using a long-term program of observations to search for and characterize disks of gas and dust.

TL;DR: In this article, ISO Short-Wavelength Spectrometer observations of H 2 pure-rotational line emission from the disks around low and intermediate-mass pre-main-sequence stars as well as from young stars thought to be surrounded by debris disks are presented.

Envelope structure on 700 AU scales and the molecular outflows of low-mass young stellar objects
TL;DR: Trends support the hypothesis that outflows are driven by accretion through a disk, with a global mass infall rate determined by the mass and density of the envelope.
