Globular Clusters Rotate at Heart

Globular Clusters Rotate at Heart

AUSTIN, Texas — Astronomers from The University of Texas at Austin and Germany’s Max Planck Institute for Extraterrestrial Physics (MPE) recently found a surprise when studying some of the oldest star clusters in our galaxy. The stars at the centers of these clusters are rotating around a common axis. It was previously thought any central rotation would have been long erased, leaving the central stars to random orbits. The work has been accepted for publication in the Astrophysical Journal Letters.

Astronomers Find Sun’s ‘Long-Lost Brother,’ Pave Way for Family Reunion

Finding the Sun's 'Long-Lost Brother'

AUSTIN — A team of researchers led by University of Texas at Austin astronomer Ivan Ramirez has identified the first “sibling” of the Sun — a star that was almost certainly born from the same cloud of gas and dust as our star. Ramirez’ methods will help other astronomers find other “solar siblings,” work that could lead to an understanding of how and where our Sun formed, and how our solar system became hospitable for life. The work will be published in the June 1 issue of The Astrophysical Journal.

Sky Survey Captures Key Details of Cosmic Explosions

Sky Survey Captures Details to Cosmic Explosions

A pair of recently published studies shed light on the study of the exploding stars known as supernovae. One of these teams includes University of Texas at Austin supernova expert and professor J. Craig Wheeler.

“We are in a new world of identifying supernova progenitor stars and the explosions very early, allowing more thorough study,” Wheeler said. “The event iPTF13bvn allowed both,” he added, referring to the study published September 20 in The Astrophysical Journal.
