An article published in the journal “Monthly Notices of the Royal Astronomical Society” describes the discovery of a protostar called G11.92-0.61 MM1. A team of astronomers led by John Ilee from the University of Cambridge’s Institute of Astronomy, UK, identified this object in a key stage in the birth of a star. It has a mass that is already more than thirty times that of the Sun and is still attracting materials from the molecular cloud in which it’s forming.
An article accepted for publication in “The Astrophysical Journal” describes a research on the exoplanet GJ 1132b, taken as an example of a rocky planet orbiting close to a red dwarf star. A team of astronomers led by Laura Schaefer of the Harvard-Smithsonian Center for Astrophysics (CfA) used computer models to simulate the evolution of that type of planet’s atmosphere concluding that could be thin and contain oxygen.
At the workshop “Chandra Science for the Next Decade” being held in Cambridge, Massachusetts, a new image was presented showing a supernova remnant called G11.2-0.3 obtained using NASA’s Chandra X-ray Observatory. For years these were considered the remnants of the supernova recorded by the Chinese in 386 A.D. and for this reason known as SN 386 but new exams indicate that it was a different supernova.
An article published in “The Astrophysical Journal Supplement Series” describes a research on brown dwarfs, objects on the border between stars and planets. A team of researchers led by Jacqueline Fahery of the Carnegie Institution examined the characteristics of 152 young brown dwarfs and concluded that their atmospheres’ properties might be the behind their differences.
An article published in the journal “Nature” describes a research about the molecular cloud located behind the Orion Nebula. A group of researchers used the HAWK-I instrument installed on ESO’s Very Large Telescope (VLT) and the ALMA radio telescope, both ESO’s, to look at key moments of astrochemical phenomena, meaning the chemical reactions that take place in space and in this case in that area and one day will lead to the birth of new stars.
