Astronomers Discover Rocky Planet Orbiting Nearest Star, Proxima Centauri

Nearest Star, Proxima Centauri, Has a Planet

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.

A New Kind of Black Hole, Once a Theory, Now Firmly within Observers’ Sight

A New Kind of Black Hole

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

Young 'Super-Neptune' Offers Clues to 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.

High School Student Helps Discover New Planet, Calculates Frequency of Jupiter-like Planets

Student Discovers Planet, Probes Frequency of Jupiters in Systems

AUSTIN — High school senior Dominick Rowan of Armonk, New York, is making discoveries about other worlds. Working with University of Texas at Austin astronomer Stefano Meschiari, Rowan has helped to find a Jupiter-like planet and has calculated that this type of planet is relatively rare, occurring in three percent of stars overall.
