Minor-Object News on 26 July '07
- "International Consortium Is Created to Build World's Largest Submillimeter Telescope," Caltech 25 July - Quote: "Because submillimeter-wavelength astronomy is especially effective for imaging phenomena that do not emit much visible light, the [Cornell Caltech Atacama Telescope (CCAT] will allow observations of stars and planets forming from swirling disks of gas and dust, will make measurements to determine the composition of the molecular clouds from which the stars are born [etc.]... The Atacama telescope will be located at an 18,400-foot altitude atop Cerro Chajnantor in Chile's Atacama Desert... Of the projected $100 million cost, $20 million will go to state-of-the-art instrumentation. In particular, large [widefield] submillimeter cameras will complement the huge size of the dish, which, at 25 meters, will have more than twice the area of the largest submillimeter telescope currently in existence. The new cameras are made possible by recent developments in sensitive superconducting detectors." - Note: The CCAT Solar System science page states that the telescope will be capable of detecting Kuiper Belt objects "to sizes of order 100 km, making possible a statistical investigation of both the size distribution and surface properties of those objects." To be completed in 2013, CCAT sounds like it could one of several advanced observatories (Pan-STARRS after 2008, DCT after 2010, Gaia after 2011, LSST and JWST after 2013) that might be able to find and help study follow-on Kuiper Belt targets for New Horizons after it passes Pluto in 2015. When the NASA mission left Earth last year there were no known possibilities, and some of the observing facilities most likely to eventually help solve that problem were still in their planning or construction phases.
- IOTA meeting: David Dunham today updated his IOTA Meeting page with his presentations, and other presentations from that event last week are available on Brad Timerson's North American Asteroid Occultation page.
- "Increasing Chance of Meteors," Sky & Telescope 25 July - Quote: "A couple of minor showers with radiants in Capricornus are currently in progress, and the moderately strong Southern Delta Aquarids peak over the weekend... Things start to get really exciting in early August, when the Moon departs from the evening sky."
- "Young Stars Swim in Pools of Molecular Hydrogen," Gemini Observatory 27 June - Quote: "Studying the gas content of protoplanetary disks around young stars is an important step in understanding the formation of planetary systems. Molecular hydrogen is one of the main constituents of the atmospheres of giant planets and so must be present in the disks for Jupiter-like planets to form... Detecting molecular hydrogen emission associated with disks has proven challenging, even with 8- to 10-meter class telescopes and advanced instruments." - Note: See the related preprint below, "Molecular Hydrogen emission from disks."
Minor-Object Science on 26 July '07
- "Molecular Hydrogen emission from disks in the eta Chamaeleontis cluster" by Ramsay Howat, Suzanne K. with Jane S. Greaves, abstract & PDF at arXiv.org June 2007 - Quote: "Disks in the 6 Myr old cluster eta Chamaeleontis were searched for emission from hot H2. Around the M3 star ECHAJ0843.3-7905 we detect circumstellar gas orbiting at ~2 AU. If the gas is UV-excited, the ro-vibrational line traces a hot gas layer supported by a disk of mass ~0.03Msolar, similar to the minimum mass solar nebula. Such a gas reservoir at 6 Myr would promote the formation and inwards migration of gas giant planets." - Note: See related news release above.
- "Cooling of young stars growing by disk accretion" by Rafikov, Roman, abstract & PDF at arXiv.org 26 July - Quote: "In the initial formation stages young stars must acquire a significant fraction of their mass by accretion from a circumstellar disk that forms in the center of a collapsing protostellar cloud... We study the impact of irradiation of the stellar surface produced by the hot inner disk on properties of accreting fully convective low-mass stars, and also look at objects such as young brown dwarfs and giant planets. At high accretion rates ... intrinsic luminosity integrated over the whole stellar surface is reduced compared to the non-accreting case ... potentially leading to the retardation of stellar contraction. Stars and brown dwarfs irradiated by their disks tend to lose energy predominantly through their cool polar regions while young giant planets accreting through the disk cool through their whole surface."
- "Subsonic Mechanical Alignment of Irregular Grains" by Lazarian, Alex with Thiem Hoang, abstract & PDF at arXiv.org 26 July - Quote: "We show that grains can be efficiently aligned by interacting with a subsonic gaseous flow... Note, that aligned grains were reported not only for the ISM, but also comets and circumstellar regions. They [are] also likely to be present in the disks around evolved and young stars."
- "Radiative torque alignment: Essential Physical Processes" by Hoang, Thiem with Alex Lazarian, abstract & PDF at arXiv.org 26 July - Quote: "We study physical processes that affect the alignment of grains subject to radiative torques (RATs)."
