Famous Red Star Betelgeuse is Spinning Faster than Expected; May Have Swallowed a Companion 100,000 Years Ago
AUSTIN — Astronomer J. Craig Wheeler of The University of Texas at Austin thinks that Betelgeuse, the bright red star marking the shoulder of Orion, the hunter, may have had a past that is more interesting than meets the eye. Working with an international group of undergraduate students, Wheeler has found evidence that the red supergiant star may have been born with a companion star, and later swallowed that star. The research is published today in the journal Monthly Notices of the Royal Astronomical Society.
Pasadena, Calif. — The Giant Magellan Telescope Organization (GMTO) today announced the appointment of Walter E. Massey, PhD, and Taft Armandroff, PhD, to the positions of Board Chair and Vice Chair, respectively.
An international team of astronomers including Michael Endl of The University of Texas at Austin have found clear evidence of a planet orbiting Proxima Centauri, the closest star to the Sun. The long-sought new world, called Proxima b, orbits its cool red parent star every 11 days and has a temperature suitable for liquid water to exist on its surface. This rocky world is a little more massive than Earth and is the closest known exoplanet to us — and may be the closest possible abode for life outside our solar system.
AUSTIN — Astronomers Aaron Smith and Volker Bromm of The University of Texas at Austin, working with Avi Loeb of the Harvard-Smithsonian Center for Astrophysics, have discovered evidence for an unusual kind of black hole born extremely early in the universe. They showed that a recently discovered unusual source of intense radiation is likely powered by a “direct-collapse black hole,” a type of object predicted by theorists more than a decade ago. Their work is published today in the journal Monthly Notices of the Royal Astronomical Society.
Texas Astronomer Finds Young 'Super-Neptune,' New Planet Offers Clues to the Origin of Close-in Exoplanets
AUSTIN — A team of astronomers led by Andrew Mann of The University of Texas at Austin has confirmed the existence of a young planet, only 11 million years old, that orbits extremely close to its star (at 0.05 AU), with an orbital period of 5.4 days. Approximately five times the size of Earth, the new planet is a "super-Neptune" and the youngest such planet known. The discovery lends unique insights into the origin of planetary system architectures.
For most of their lives, galaxies are lush environments for turning gas into stars. Until they aren’t.

Astronomer Brendan Bowler of The University of Texas at Austin has been awarded a competitive Hubble Fellowship from NASA and the Space Telescope Science Institute (STScI), science center for the Hubble Space Telescope.
“I congratulate Brendan Bowler on winning one of the most prestigious fellowships in astronomy to continue his work at McDonald Observatory," said Taft Armandroff, the observatory’s director.
