Nasty 1 star
2015-05-22 08:49:26

Astronomers using NASA's Hubble Space Telescope have uncovered surprising new clues about a hefty, rapidly aging star whose behavior has never been seen before in our Milky Way galaxy. Astronomers have nicknamed it 'Nasty 1', a play on its catalog name of NaSt1.

lopsided star

By analyzing the remnant of a recently-exploded star, researchers have confirmed what computer models have long predicted – when stellar giants die, they do so in a lopsided fashion, as the core of the star is flung off in one direction and debris is sent flying the opposite way.

wide orbit pulsar

A newly discovered pulsar has the widest orbit ever discovered around a neutron star and is part of a rare double neutron star system, and could help astronomers gain new insight as to how such systems form and evolve, the National Radio Astronomy Observatory (NRAO) has announced.

Stars Gather in 'Downtown' Milky Way

Braaaaaains. A mysterious high-energy X-ray signal detected by NuSTAR could be the sounds of “zombie” stars feeding on the “brains” of nearby stellar companions, according to research published recently in the journal Nature.

In Star Wars, the Death Star is a massive spaceship capable of destroying a planet with just one shot of its laser, but a recently-discovered white dwarf star may have ripped apart a planet at its core by coming too close to it, making it a real-life Death Star.

Unlike most types of stars, which are just as likely as not to have companions and be part of a binary system, an ancient type of variable stars known as RR Lyrae stars seemed to always live out their lives on their own – something that has long puzzles astronomers.

NASA studied the 'crime scene' left behind from an explosion of an Ia supernova and discovered that a single white dwarf star is to blame.

million stars forming
2015-03-19 12:09:00

Astronomers have identified a previously invisible stellar cluster currently forming over 1 million new stars, according to a report in the journal Nature.

brown dwarf star
2015-02-19 09:48:24

Not much escapes the sight of the European Southern Observatory’s Very Large Telescope in Chile, but astronomers using the powerful four-telescope array have been unable to pinpoint the location of a brown dwarf star believed to be orbiting a nearby binary star system.

perseus

Catching the formation of a single star is a tough thing to do, and yet a large team of international astronomers has announced the discovery of four stars all forming in the same system.

X-Ray Astronomy -- Although the more energetic X-rays (E > 30 keV) can penetrate the air at least for distances of a few meters (they would never have been detected and medical X-ray machines would not work if this was not the case) the Earth's atmosphere is thick enough that virtually none are able to penetrate from outer space all the way to the Earth's surface. X-rays in the 0.5 - 5 keV range, where most celestial sources give off the bulk of their energy, can be stopped by a few...

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...

X-ray Pulsar -- This dramatic artist's vision shows a city-sized neutron star centered in a disk of hot plasma drawn from its enfeebled red companion star. Ravenously accreting material from the disk, the neutron star spins faster and faster emitting powerful particle beams and pulses of X-rays as it rotates 400 times a second. Could such a bizarre and inhospitable star system really exist in our Universe? Based on data from the orbiting Rossi X-Ray Timing Explorer (RXTE) satellite,...

X-ray Burster -- X-ray bursters are a class of binary stars which are luminous in X-rays. They contain a neutron star and a low-mass companion star. The companion fills its Roche lobe and therefore the neutron star is accreting matter from it. The inflowing gas forms an accretion disk around the neutron star. Sometimes X-ray bursters show a sudden increase in their X-ray luminosity, called X-ray burst. All properties of the X-ray bursts can be explained assuming that they result from...

X-ray Binaries -- X-ray binaries are a class of binary stars that are very luminous in X-rays. The X-rays are produced by matter falling from one component (usually a relatively normal star) to the other component, which is a neutron star or a black hole. The infalling matter releases gravitational potential energy, up to several tens of per cent of its rest mass as X-rays. (Hydrogen fusion releases about 0.7 per cent of rest mass) X-ray binaries are further subdivided into...
