Abstract: On presente des observations optiques des etoiles, une carte dans la raie radio J=1-0 de C 18 O et une cartographie de l'extinction visuelle par la poussiere deduite de comptages d'etoiles dans la region du complexe de Taurus situee devant (et aux environs) de la position de la radiosource 3C 111. On a determine la distance du nuage (380±20 pc). La carte revele l'existence d'une grande condensation (∼4,2 pc de diametre) avec de petits grumeaux (∼0,1-0,5 pc) ou l'extinction visuelle est superieure a 4 mag

TL;DR: In this paper, a multiblob model was used to reproduce the high energy spectra observed for each object, while also allowing predictions of the potential very high energy fluxes to be produced.

THE UNUSUAL HERBIG Ae/Be STAR XY Per A
TL;DR: In this paper, the results of an investigation of XY Per based on photoelectric observations in the Stromgren system are presented, and it is shown that the brighter component in the binary system XY Per AB, classified earlier as A2 II, is a variable of the Herbig Ae/Be type.

TL;DR: In this paper, it is shown that magnetic field is the most efficient agent to redistribute energy and momentum between the reservoirs of kinetic energy and the clouds, thus providing them with kinetic support over timescales much longer than 107 yr.
