An article published in the journal “Monthly Notices of the Royal Astronomical Society” describes a research for possible planets in formation orbiting the pulsar Geminga. The astronomers Jane Greaves and Wayne Holland used the James Clerk Maxwell Telescope (JCMT) in Hawaii to conduct observations at submillimetric wavelengths and understand the mechanisms of planet formation in a system after a supernova.
An article submitted for publication in the journal “Monthly Notices of the Royal Astronomical Society” describes a research on the supermassive black hole at the center of the galaxy NGC 5195, which is undergoing some sort of indigestion. Using data collected with various telescopes, a team of astronomers at the University of Manchester discovered that the black hole causes chaotic events in its galaxy. Among the causes there’s its interaction with a much larger galaxy called NGC 5194 or Whirlpool galaxy.
Two telescopes in Hawaii were used for new observations of the planet Jupiter and in particular of its famous Great Red Spot. They were conducted to support NASA Juno space probe’s mission, which on July 10 will fly over the giant jovian storm. The Gemini North telescope was used with special near-infrared filters to produce specific colors that can penetrate Jupiter’s upper atmosphere and clouds. The Subaru telescope’s COMICS instrument was used with mid-infrared filters.
An article published in the journal “Nature Astronomy” describes a study of the IRAS 04191+1523 system, consisting of two low-mass newborn stars. A team of astronomers led by Jeong-Eun Lee of Kyung Hee University, Korea, used the ALMA radio telescope to figure out how pairs of little stars form. The discovery that the two stars’ rotation axes are misaligned led them to conclude that a turbulence caused the fragmentation of the gas cloud from which they were born.
An article published in the journal “Astronomy & Astrophysics” describes a study of the star Betelgeuse conducted using the ALMA radio telescope. This extraordinary instrument studied for the first time the surface of a star to get the highest resolution images ever obtained of Betelgeuse. This made it possible to obtain new data about its atmosphere and its asymmetries that will help to better understand red supergiants in the phases preceding a supernova.
