... Kepler's Supernova Remnant in X Rays . ... Recent X-ray data and images of Kepler's supernova remnant taken by the orbiting Chandra X-ray Observatory has shown relative elemental abundances typical of a Type Ia supernova , and further indicated that the progenitor was a white dwarf star that exploded when it accreted too much material from a companion Red Giant star and went over Chandrasekhar's limit . ...

... He made observations of a supernova (literally: nova= "new star") in 1572 (we now know that a supernova is an exploding star, not a new star). ... Brahe's meticulous observations showed that the supernova did not change positions with respect to the other stars (no parallax). ... This was early evidence against the immutable nature of the heavens, although Brahe did not interpret the absence of parallax for stars correctly, as we discuss below. Brahe made careful observations of a comet in 1577. ...

An Ancient Universe: How Astronomers Know the Vast Scale of Cosmic Time . SUPERNOVA 1987a . This Hubble Space Telescope image shows the remnant of a supernova a star that blew itself to pieces. We first saw the light of the explosion on Earth in 1987, and this image was taken in 1994. The remnant of the explosion itself is the blob of stuff in the center; the rings are regions of material ejected by the star earlier in its death throes. ... Return to An Ancient Universe . ...

... News . ... Star Atlas . ... stars . ... Astronomers discover a new kind of supernova . This new class of supernova, type Iax, is fainter and less energetic than type Ia. ... Today, astronomers are reporting their discovery of a new kind of supernova called type Iax. ... Based on a variety of observational data, the team concluded that a type Iax supernova comes from a binary star system containing a white dwarf and a companion star that has lost its outer hydrogen, leaving its helium dominated. ...

... To avoid extensive numerical calculations in the statistical simulations, we treat the continuous evolution of each binary component as a sequence of a finite number of basic evolutionary states (for example, main sequence, red (super)giant, helium (Wolf-Rayet) star,     hot WD), in which stellar parameters significantly differ from each other. ...

... This Instrument Science Report discusses a phenomenon of GHRS performance that arose as a result of observations as part of Cycle 5 program 6075. ... Program 6075 was highly unusual in that it obtained a series of short-exposure spectra of a star over many orbits in ACCUM mode and during the occultation portion of each orbit a similar series of wavelength calibration exposures were obtained, also with ACCUM. ... Also, more typically a PI will obtain a single (or a few) long exposures as an ACCUM. ...

Dr John Chambers has made detailed computer simulations of the origin and formation of the Earth and the inner planets. These build upon earlier work by Chambers and George Wetherill, of the Carnegie Institution of Washington, whose computer calculations had predicted that planets would tend to have elliptical orbits rather than the almost-circular ones we see in the Solar System. ...
