NEW ASTROPHYSICS RESEARCH REPORTED FROM E.H. NIKOGOSSIAN AND CO-AUTHORS
Science Letter
January 12, 2010
"Three new Herbig-Haro and 12 emission stars, mainly belonging to the
T Tau class, have been discovered in a study of the region of the GM
1-64 and GM 2-4 nebulae in the direction of the galactic anticenter.
GM 1-64 and GM 2-4 are typical cometary nebulae illuminated by emission
stars," scientists in Armenia report (see also Astrophysics).
"In GM 2-4 the central star is surrounded by a dense dust envelope and
is observed only in the IR. Two stellar-like sources which are bright
in the IR are found in this same region and can be regarded as young,
Class 1 stars. One of them (CPM 19) is surrounded by a compact group
of fainter PMS objects," wrote E.H. Nikogossian and colleagues.
The researchers concluded: "It is found that CPM 19 shows up clearly in
the optical range and undergoes large amplitude brightness variations."
Nikogossian and colleagues published their study in Astrophysics
(SEARCH FOR HH-OBJECTS AND EMISSION STARS IN STAR FORMATION REGIONS.
