The dramatic end of a starry couple

The death fight between two stars has been captured in pictures by astronomers with the Atacama Large Millimeter/Submillimeter Array (ALMA). The gas cloud, which appears to consist of multiple rings, is the remains of the binary star system HD101584. “A nearby low-mass companion star was engulfed by the giant,” explains Hans Olofsson of the Chalmers University of Technology, Sweden, who is the lead author of a study on this object, now published in the journal, Astronomy & Astrophysics. The ALMA image shows vividly what happened during this confrontation, described in a press release from the European Southern Observatory (ESO), which…

Big baby stars grow the same way as small baby stars

The protostellar object, G353.273+0.641, which is located 5500 light-years from Earth in the constellation Scorpio, is still a baby. It ignited only around 3000 years ago; astronomically, that is an extremely short amount of time. Nevertheless, G353 is already ten-times heavier than the Sun, and it’s still growing. For the first time, researchers were able to catch a direct glance from above of such a massive protostar and its surroundings using the Atacama Large Millimeter/submillimeter Array (ALMA). In this way, they were able to determine that apparently size doesn’t matter. G353, in any case, acts no different than other…
