BYURAKAN,Armenia—Astronomers from the Byurakan Astrophysical Observatory in Armenia fill discovered a strong outburst of the embedded young stellar thing (YSO) designated UKIDSS-J185318.36+012454.5. The researchers presented their discovery in a paper published on Dec. 30 on the arXiv preprint server, Phys.org reports. The images of UKIDSS-J185318.36+012454.5 in different wavelengths (Image: Nikoghosyan et al., and 2016) The work was done when a group of researchers led by Elena Nikoghosyan combed through the data and images provided by the United Kingdom Infrared Telescope (UKIRT) in Hawaii to search for evidence of outburst in star forming regions. They used the archival infrared and submillimeter data from UKIRT Galactic Plane Survey (UKIDSS GPS) and found that an outburst took place in UKIDSS-J185318.36+012454.5 in the period of 2004-2006. UKIDSS-J185318.36+012454.5 is located in the vicinity of the IRAS 18507+0121 source and most likely belongs to the massive star-forming region associated with GAL 034.4+00.23 HII region. The thing is at least 5000 light years absent from the earth and its area contains massive protostars with an age of about 100000 years,as well as a low-mass stellar population approximately 1 million years ancient. The stellar thing was classified as an intermediate mass YSO less than 100000 years [...]
