"Recent studies of the star formation region BBW 36 and associated
molecular clouds are presented. The (CO)-C-12 (1-0) observations,
carried out with the 15-m SEST (Swedish-ESO) telescope (Cerro La Silla,
Chile), revealed the existence of cloud a, connected with BBW 36 and
of cloud b, having elongation in SE-NW direction," scientists writing
in the journal Astrophysics report (see also Astrophysics).
"A red-shifted molecular outflow with velocity similar to+5 km/s
(with respect to cloud a), having a direction parallel to the line of
sight, was also observed. VLA observations showed the presence of a
source VLA 2 at 3.6 cm with an elongation in the N-S direction. It is
suggested that the VLA 2 source coincides with a dust disc (surrounding
the object BBW 36). The star 3, which is one of the YSOs in the
star-forming region BBW 36 and is connected with a bright comma-like
nebula, can be the source of the molecular outflow. The star 3 has
very high IR colors and is associated with an IRAS point source IRAS
07280-1829, which has IR colors, typical for an IRAS point source,
connected with a water maser. On the 2MASS K image of BBW 36 we can
see the existence of a bright nebula; a group of stars is embedded
in that nebula, and among these stars there are stars with dust discs
(or envelopes)," wrote A.L. Gyulbudahgian and colleagues.
The researchers concluded: "On the 2MASS K image several spiral jets
are also present, some of them with a condensation at the end."
Gyulbudahgian and colleagues published their study in
