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.

Newly discovered Hyades planet has potential

by Rebecca Johnson

AUSTIN — University of Texas at Austin astronomer Andrew Mann and colleagues have discovered a planet in a nearby star cluster which could help astronomers better understand how planets form and evolve. The discovery of planet K2-25b used both the Kepler space telescope and the university’s McDonald Observatory, and is published in a recent issue of The Astrophysical Journal.

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.

Texas Astronomer Solves Mystery of 'Born Again' Stars with Hubble Space Telescope

Solving the Mystery of 'Born Again' Stars

by Rebecca Johnson

AUSTIN — University of Texas astronomer Natalie Gosnell has used Hubble Space Telescope to better understand why some stars aren’t evolving as predicted. These so-called “blue stragglers” look hotter and bluer than they should for their advanced age. It’s almost as if they were somehow reinvigorated to look much younger than they really are.

Early Galaxies More Efficient at Making Stars, Hubble Survey Reveals

Early Galaxies More Efficient at Making Stars

AUSTIN — A study published in today’s Astrophysical Journal by University of Texas at Austin assistant professor Steven Finkelstein and colleagues reveals that galaxies were more efficient at making stars when the universe was younger. The announcement explains the team’s discovery, announced in the journal’s September 1 issue, that there are a lot more bright, highly star-forming galaxies in the early universe than scientists previously thought.
