Astronomers find giant planet around very young star Cl Tauri

A team of astronomers from Rice, Lowell Observatory, the University of Texas, and NASA's Jet Propulsion Laboratory have discovered a giant planet in an environment that upends conventional wisdom, an intact circumstellar disk around a very young star.

Astronomers Discover Rocky Planet Orbiting Nearest Star, Proxima Centauri

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. The research will be published in the journal Nature on Aug 25. more..

A New Species of Black Hole, "Direct-Collapse", Once a Theory, Now Firmly within Observers’ Sight

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. more..

Texas Astronomer Finds Youngest 'Super-Neptune'

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. more..
