Is Multitasking rotting our kids brains
ArtsJournal's headline; USA Today said «So much media, so little attention span»
- Speaking of Multi-Tasking ... this is our token non-astro "wet" news item ;-)

Is this a brown dwarf or an exoplanet? [updated]
«Using the ESO VLT, astronomers have found a companion to the T-Tauri star GQ Lupi. Comparing with archive data, the astronomers could confirm that the two objects move together in the sky. The companion, roughly 250 fainter than GQ Lupi A, is located at 100 AU from it and is found to be a cool and small object. Its exact nature - exoplanet or brown dwarf – is still unclear.»
- This is the same one reported previously here, but now there's an on-line pre-print linked from the ESO PR.

Superglue Of Planet Formation: Sticky Ice
«Scientists at the Department of Energy's Pacific Northwest National Laboratory, reporting in the current issue of Astrophysical Journal, offer a cool answer to the planet-formation riddle: Micron-wide dust particles encrusted with molecularly gluey ice enabled planets to bulk up like dirty s nowballs quickly enough to overcome the scattering force of solar winds.»
- Super-Low temperature "fluffy ice" is much softer than regular ice, and thus impacts are very inelastic, so things can clump up with gravity capture instead of bouncing with escape velocity.

Special RAS-NAM2005 Section

The Royal Astronomical Society's on-going National Astronomers Meeting (RAS-NAM 2005) in Birmingham, UK is a major source of astronomical Press Releasees this week; the Conference abstracts go on for 33 sessions, or 97 pages with 4-5 abstracts per page.



New solar flare evidence may solve mystery
«An international group of scientists has discovered important new evidence that points to the cataclysmic events that trigger a solar flare and the mechanisms that drive its subsequent evolution. The new results were obtained by using the SOHO spacecraft to study one of the most powerful solar flares of recent years.»
