An international group of astronomers, including Dr Simon Jeffery of the Armagh Observatory, has used the Hubble Space Telescope to verify the origin of a very unusual and rare type of star. The group's studies confirm that the so-called "extreme helium stars" are formed by the merger of two white dwarf stars. ... One, dubbed the final-flash (FF) model, suggests an outer helium layer of a cooling white dwarf ignites, producing an extra thermal pulse that balloons the star into a giant. ...

... This paper describes the main algorithms used by the Einstein Level One processing to create the exposure masks and the background maps for Einstein IPC images, and how these algorithms were recreated in the IRAF environment. Our goal was to recreate the algorithms used by the Level One Processing to create exposure masks and background maps for Einstein Image Proportional Counter (IPC) data (cf. sections 2.5 and 2.7 of Harnden et al. ...

This ASKAP data release includes a continuum simulation. This was created in the following way: * The SKADS S3-SEX simulation (Wilman et al 2008) was used as the source catalogue from which a sky model image was created. This sky model was used as input into a telescope simulation. ... We also provide a catalogue of sources extracted from that image (using the ASKAPsoft version of the Duchamp source finder), and a matching annotation file suitable for use with kvis. ...

... Our Sun is part of a huge wheel-shaped collection of stars. ... Astronomers have long suspected it was a very massive black hole, and that every galaxy had such a central mass, created early in the history of the universe. ... However, unless that object happens to be headed directly at the black hole (a relatively small target) it will just swing around and fly away again, like a comet making a pass at the Sun. The velocity acquired in falling towards the black hole also helps it escape. ...

... STScI-PRC98-21 A BRIGHT RING OF STAR BIRTH AROUND A GALAXY'S CORE An image from NASA's Hubble Space Telescope reveals clusters of infant stars that formed in a ring around the core of the barred-spiral galaxy NGC 4314. ... This close-up view by Hubble also shows other interesting details in the galaxy's core: dust lanes, a smaller bar of stars, dust and gas embedded in the stellar ring, and an extra pair of spiral arms packed with young stars. ... However, they are older than those in the ring. ...

... In spite of the lack of rich clusters around us and the presence of large volumes completely free from galaxies (voids), the mean luminosity densities and the mean density of hydrogen mass in the Local Universe is one and a half - twice as high as their mean global values. However, the mean local density of the baryon mass is only 2% of the critical density of the Universe, which is twice as less as the baryon density from the nucleosynthesis data (local paradox of the baryon mass). ...
