An article published in “The Astrophysical Journal Letters” describes the discovery of the relics of an ancient globular cluster in the Milky Way’s central area. A team of astronomers led by Dante Minniti (Universidad Andrés Bello, Santiago, Chile) and Rodrigo Contreras Ramos (Instituto Milenio de Astrofísica, Santiago, Chile) used observations from the “Variables in the Via Lactea with VISTA” (VVV) survey carried out with ESO’s VISTA telescope to discover the ancient stars of type RR Lyrae for the first time in that area.
An article published in “Astrophysical Journal Letters” describes a research on the IRS 43 system, which turned out to be really extraordinary because it’s formed by two very young stars each surrounded by a disk of gas but they share a third much bigger disk. A team of scientists from the Niels Bohr Institute, University of Copenhagen, used the ALMA radio telescope to discover this structure never seen before.
An article published in “The Astrophysical Journal” describes a research on the huge plasma blobs ejected by the red giant star V Hydrae. A team of astronomers led by Raghvendra Sahai of NASA’s JPL used the Hubble Space Telescope to study this phenomenon and concluded that the plasma blobs come from another star, a companion of V Hydrae that we can’t see.
An article published in “The Astrophyisical Journal” describes the discovery of the first gamma-ray binary found outside the Milky Way, called LMC P3. A team of researchers led by Robin Corbet at NASA’s Goddard Space Flight Center used the Fermi space telescope to discover this couple in the Large Magellanic Cloud formed by a giant blue star and a companion that might be a neutron star or a black hole that are interacting producing cyclic gamma-ray emission.
An article published in the journal “Science” describes a research about the structure around the young star Elias 2-27. A team led by astronomer Laura Perez of the Max Planck Institute for Radio Astronomy in Bonn, Germany, used the ALMA radio telescope to detect the spiral-shaped structure around the star, the first of its kind ever observed.
