... September 5, 1998 . The Pulsar Powered Crab . Credit: J. Hester and P. Scowen ( ASU ), NASA . ... Using a stunning series of visible light images taken with the Hubble Space Telescope (HST) , astronomers have discovered spectacular pulsar powered motions within the Crab nebula. Highlights of this HST Crab "movie" show wisps of material moving away from the pulsar at half the speed of light, a scintillating halo, and an intense knot of emission dancing, sprite-like, above the pulsar's pole. ...

We report far-infrared and submillimeter observations of supernova 1987A, the star whose explosion was observed on 23 February 1987 in the Large Magellanic Cloud, a galaxy located 160,000 light years away. ... The intensity and spectral energy distribution of the emission suggest a dust mass of about 0.4 to 0.7 times the mass of the Sun. ... Our observations imply that supernovae can produce the large dust masses detected in young galaxies at very high redshifts. ... ADS Citation Query . ...

The radiopulsar PSRB1259-63 in a massive binary has an extremely high eccentricity (Johnston et al. ... We have assumed that explosion occurs at a random moment on the orbit and all the mass thrown off by a star instantly leaves the system because the characteristic velocity of matter from the exploded star is much higher than the orbital velocity. ...

... In collaboration with Drs Van Genderen (Leiden, Holland) and Sterken (Brussels, Belgium) papers XV and XVI in the series `Light Variations of Massive Stars' were published. These dealt with the brightness variations of several massive stars in the two nearest neighbour galaxies, namely six stars (R85, R99, R103, R110, R123 and R128) in the Large Magellanic Cloud (LMC) and two (R42 and R45) in the Small Magellanic Cloud (SMC). ...

... Stars . ... To understand what has happened we need to consider an often-overlooked class of object, the white dwarfs. New research shows that some old stars known as white dwarfs might be held up by their rapid spins, and when they slow down, they explode as Type Ia supernovae. ... However, give a white dwarf a very close companion star and you could have an explosion visible across the Universe. ... This, however, is not the only catastrophe that can befall such a white dwarf star. ...

Astronomers have found a radio pulsar with a companion at least 11 times the mass of the Sun - the most massive pulsar companion known. The identity of the companion is uncertain: it may be a massive late-type (red) star, a massive but compact blue star, or possibly a black hole. ... The probability of this late-type star being there by chance, and not being the pulsar companion, is only about 1.3%," says team member Dr. Fernando Camilo of Columbia University. ... So what can the companion be? ...

Diffuse interstellar bands (DIBs) and atomic lines are observed as interstellar absorptions in GALAH and other massive spectroscopic stellar surveys. By observing a given DIB toward many stars which are nearly in the same direction, but at different distances, one can reconstruct absorption sites along the line of sight. ...

... Dr. Stella Kafka . Thursday, Dec 10, 2015 at 8:00 PM . Type I Supernovae are massive stellar explosions that result from an interaction between a white dwarf and a companion whose mass it accrues in a close binary system. When the white dwarf’s mass reaches 1.4 that of the sun, the supernova occurs. ...
