Star Cluster Study Inspires New Ideas On How Sun-Like Stars Form
2014-05-08 10:15:43

Brett Smith for redOrbit.com - Your Universe Online The prevailing theory on star cluster formation states that gravity causes a giant cloud of gas and dust to condense to concentrations that trigger the ignition of stars at the center of the cloud. However, according to a new study based on data from NASA's Chandra X-ray Observatory and infrared telescopes, some of the oldest stars in known clusters sit on the exterior of their groups. The study researchers focused on two clusters...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Most stars move around the galaxy in well-defined orbits, pulled under the influence of the Milky Way’s gravity. It is the predictable motion of the stars around the Milky Way’s supermassive black hole core that gives the galaxy its spiral structure. There are, of course, deviations from the norm, but on average the stars move at a leisurely pace of roughly 500,000 miles per hour. But this is not always the case. In...

interstellar medium solves pulsar mystery

[ Watch the Video: Radio Wave Emission From A Pulsar ] John P. Millis, Ph.D. for redOrbit.com - Your Universe Online When a massive star, typically around 10 times the mass of our Sun, reaches the end of its main-sequence life, a series of events begins that eventually leads to a brilliant supernova. The shockwave from the event ejects most of the material into the surrounding interstellar medium, leaving a brilliant blanket of glowing gas that hangs in the sky for thousands of years....

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online In the normal course of evolution, galaxies initially formed stars as clouds of hydrogen and helium collapsed. Eventually the density and temperature of the cores would ignite nuclear fusion, allowing them to shine during what we call the main sequence phase of their lives. Eventually, stars will fuse heavier and heavier elements, with stars like our sun eventually culminating as balls of carbon and oxygen – in varying...

Harvard-Smithsonian Center for Astrophysics The galaxy known as M87 has a fastball that would be the envy of any baseball pitcher. It has thrown an entire star cluster toward us at more than two million miles per hour. The newly discovered cluster, which astronomers named HVGC-1, is now on a fast journey to nowhere. Its fate: to drift through the void between the galaxies for all time. "Astronomers have found runaway stars before, but this is the first time we've found a runaway star...

The prominent feature that allows for the existence of life on Earth is the Sun. Radiation from our closest star provides heat and energy to our planet, driving biological processes and providing the necessary conditions for liquid water to naturally exist. But our Sun is only but one star in this vast Universe. And as it turns out, most stars are quite different than the one that illuminates our day. For this reason, scientists have, for hundreds of years, attempted to study the other...

UV Astronomy -- UV astronomy is the branch of astronomy and astrophysics which deals with objects visible in ultraviolet (UV) radiation. UV radiation ranges approximatively from 10nm (extreme UV) to 380nm (near UV). Ultraviolet line spectrum measurements are used to discern the chemical composition, densities, and temperatures of interstellar medium, and the temperature and composition of hot young stars. UV observations can also provide essential information about the evolution of...

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 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...

Variable Star -- Most stars are of nearly constant luminosity. Our own Sun is a good example which goes through practically no measurable variation in brightness. There are, however, stars which do vary in brightness, called variable stars. They fall into two main groups: Intrinsic variables These are stars which have intrinsic variations in brightness, that is the star itself gets brighter and dimmer. There are many types of intrinsic variables, the main types being: -- Mira...

  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
