Pair-Instability Supernovae: What might they look like?

How do the most massive stars explode? A new model of massive stars predicts new observational evidence.

Measuring Galaxy Star Formation

How well do the current methods of measuring the star formation rate of galaxies match then known star formation rate in simulations?

Just how far away is the Pleiades?

The Pleiades is one of the most well-known open clusters visible with the naked eye from Earth. But just how far away is the cluster? New results help determine a more accurate distance and suggest a troubling error in a previous study.

The History of the Galactic Halo

The number and luminosity distribution of white dwarfs stars can be used to help figure out the past history of the Galactic halo.

Accretion in Young Stars

What might be causing the accretion rates in newly formed stars to remain so high?

Astrophysical Classics: Cosmochronology with White Dwarfs

In today’s Astrophysical Classic, we hark back to 1987 and the introduction of a new method determining the age of the universe through the use of white dwarf stars.

A Faint Black Hole?

The authors report the discovery of perhaps the faintest black hole x-ray binary. But this conclusion is limited by the uncertainty in the distance to the object.

Blank Sky But Not Blank Information

Archival data are able to place constraints on the origin of supernova 2011fe.

Engineering at the SOAR Telescope in Chile

I recently participated in an engineering trip to the SOAR Telescope in Chile, where I helped with numerous maintenance and upgrades for the Goodman Spectrograph.

Pulsations and Evolution

Kepler finds a new binary system with a Delta Scuti pulsator.
