Lee Rannals for redOrbit.com - Your Universe Online Astronomers from the Armagh Observatory in Northern Ireland say they have discovered two unusual, heavy metal stars. The team wrote in the journal Monthly Notices of the Royal Astronomical Society that they found the stars HE 2359-2844 and HE 1256-2738 to contain extremely high concentrations of lead in their atmospheres. Naslim Neelamkodan, Simon Jeffery, Natalie Behara and Alan Hibbert said these two stars have surfaces containing...

Researchers at the University of Warwick have found a unique feuding double white dwarf star system where each star appears to have been stripped down to just its helium. We know of just over 50 close double white dwarfs but this was only the second ever eclipsing close white dwarf pair to be found. The University of Warwick astronomers Steven Parsons and Professor Tom Marsh were able to use the fact that the stars eclipse each other when seen from Earth to make particularly detailed...

A new object with an age of thousands of millions of years and a mass of  one tenth of the Sun, placing it at the frontier between low-mass stars and brown  dwarfs, has been discovered as the furthest of its class in Milky Way. Nicknamed ULAS1350, this subdwarf could become on of the key element to improve our knowledge on the first steps of the formation of our Galaxy. The team of European astronomers responsible for the discovery, composed  of members of the Instituto de...

Hertzsprung-Russell Diagram -- In stellar astronomy, the Hertzsprung-Russell diagram (H-R diagram) shows the relation between the absolute magnitude and the spectral types of stars. It was invented around 1910 by Ejnar Hertzsprung and Henry Norris Russell. There are two equivalent forms. One is the observer's form which plots the color of the star on one axis and the absolute magnitude on the other axis. The theoretician's form plots the temperature of the star on one axis and the...
