An article published in the journal “Monthly Notices of the Royal Astronomical Society” describes a study on the diffusion of binary systems composed of low-mass stars. The astronomers Sarah Sadavoy of the Smithsonian Astrophysical Observatory and Steven Stahler of the University of Berkeley studied very young stars in the molecular cloud of the constellation of Perseus concluding that that kind of stars is always born in pairs, including the Sun.

An article published in the journal “Nature Astronomy” describes a study of the massive newborn baby star Orion KL Source I. A team of astronomers led by Tomoya Hirota used the ALMA radio telescope to capture what was called the birth cry of that star and determine that its outflow’s motion and shape indicate that the interaction of centrifugal and magnetic forces in a disk surrounding the star plays a crucial role in that cry.

An article published in “The Astrophysical Journal” describes a research about the Boomerang Nebula, described as the coldest spot in the universe. A team led by Raghvendra Sahai of NASA’s Jet Propulsion Laboratory used the ALMA radio telescope to understand why the outflow of materials from the star at the center of the nebula is expanding very quickly. According to the astronomers there’s a companion and the gravitational interactions between the two stars accelerated that outflow.
