(Phys.org)—Astronomers from the Byurakan Astrophysical Observatory in Armenia have discovered a strong outburst of the embedded young stellar object (YSO) designated UKIDSS-J185318.36+012454.5. This newly detected event could provide important insights for the understanding of eruptive variability of young stars. The researchers presented their discovery in a paper published Dec. 30 on the arXiv preprint server.
