A series of articles to be published in “Astrophysical Journal” and “Monthly Notices of the Royal Astronomical Society” describe different parts of a research based on the observation of the Hubble Space Telescope’s Ultra Deep Field (HUDF) using the radio telescope ALMA. These observations show that the rate of star formation in young galaxies is closely related to their total mass in stars.
Two articles, one published in “The Astrophysical Journal Letters” and one published in the journal “Monthly Notices of the Royal Astronomical Society”, describe as many research on the supernova remnants known as RCW103. At its center a neutron star formed called 1E 161348-5055 – or simply 1E 1613 – that has been puzzling astronomers for decades for its abnormal behavior. Now two teams independently offered the same explanation: the neutron star has the characteristics of a magnetar.
ESA has published the first 3D map of the Milky Way obtained from the Gaia space probe, the most detailed of its kind ever produced. It’s a catalog of more than a billion stars with data that are two hundred more accurate than those of its predecessor, Hipparcos, whose mission lasted between 1989 and 1993.
An article published in “The Astrophysical Journal” describes a research on the globular cluster Terzan 5. An international team of astronomers led by Francesco Ferraro from the University of Bologna discovered that the stars of Terzan 5 are divided into two groups, one with an age of 12 billion years and one with an age of around 4.5 billion years, more or less like the Sun. This unique feature can help to better understand the evolution of the Milky Way.
Yesterday ESO held a press conference to announce that probably they discovered an exoplanet orbiting Proxima Centauri, the nearest star to the solar system. A team of astronomers led by Guillem Anglada-Escudé from Queen Mary University of London found what was called Proxima b, a planet a little more massive than the Earth orbiting in the habitable zone of its star.
