This schematic "cartoon" of a protoplanetary disk cross-section is from the Far-Infrared Interferometer (FIRI) ESA mission proposal (see below), which is a good general read about what isn't known and needs to be learned about protoplanetary disks. This broad research topic includes how asteroids, comets, and meteors were formed, as well as the rest of the Solar System and our own selves, of course.

Minor-Object News on 13 July '07
- Kitt Peak update: The Southwest Coordination Center issued its final news release this morning (545Kb PDF), reporting 85% containment of the Alambre Fire and that firelines on the Kitt Peak side "are cool and have been mopped up and rehabilitated." Further operations are being turned over to the local command of the Tohono O'odham Nation.
- "Star gazers set to return to Kitt Peak," KVOA-TV 13 July - Quote: "Even though it's grown to more than 7,600 acres, the fire is now 80% contained. And as firefighters finish up, the Kitt Peak Observatory is getting ready to welcome back star gazers."
- "Alambre Fire impacts U of A study of the stars," KVOA-TV 12 July - Quote: "The biggest impact of the fire has been the loss of observation time on the telescopes and the professors say that time just cannot be made up... Several hundred million dollars sit atop that mountain, used by researchers all around the world."
- "Dawn ELV Status Report," NASA KSC 13 July - Quote: "Dawn remains atop the Delta II launch vehicle at Pad 17-B. The spacecraft will be removed from the launch vehicle and returned to a payload processing facility late next week. Program managers are working to determine a specific launch date based on the launch window for the mission's science objectives, the availability of the Eastern Range, and the necessary tracking, data and telemetry support."
- "Delay of NASA asteroid belt mission to cost $20 million," Northwestern Univ. Medill Reports 12 July - Quote: "Last week NASA postponed its Dawn mission to the asteroid belt from July to September... The delay will cost the organization an additional $20-25 million... The Dawn mission has thus far cost NASA an estimated $449 million. NASA will likely produce the cash to pay for the delay of Dawn by suspending other, smaller projects, [mission PI Christopher] Russell said."
- "Giant Telescope To Start Watching Skies," AP at CBS News 13 July - Quote: "Perched atop a 7,800 foot [2,400 meter] peak on the Atlantic island of La Palma, the Great Canary Telescope [GTC] will receive its so-called 'first light' [tonight]... The telescope will have 36 hexagonal mirrors, of which 12 are already in place... [The] remaining 24 mirrors will be placed and adjusted, and the [10.4-meter] scope will be fully functional within a year."
Minor-Object Science on 13 July '07
- "FIRI -- a Far-Infrared Interferometer" by Helmich, Frank with Rob Ivison, abstract & PDF at arXiv.org 13 July - Quote: "Half of the energy ever emitted by stars and accreting objects comes to us in the FIR waveband and has yet to be properly explored. We propose a powerful Far-InfraRed Interferometer mission, FIRI, to carry out high-resolution imaging spectroscopy in the FIR. This key observational capability is essential to reveal how gas and dust evolve into stars and planets [etc.]... Perhaps most importantly, FIRI will observe all stages of planetary system formation and recognise Earth-like planets that may harbour life, via its ability to image the dust structures in planetary systems." - Note: This is a "Proposal developed by a large team of astronomers from Europe, USA and Canada and submitted to the European Space Agency as part of 'Cosmic Vision 2015-2025.'"
- "A decreased probability of habitable planet formation around low-mass stars" by Raymond, Sean N. with John Scalo & Victoria Meadows, abstract & PDF at arXiv.org 13 July - Quote: "Smaller terrestrial planets (<0.3 Earth masses) are less likely to retain the substantial atmospheres and ongoing tectonic activity probably required to support life. A key element in determining if sufficiently massive 'sustainably habitable' planets can form is the availability of solid planet-forming material. We use dynamical simulations ... and simple scaling arguments to explore the implications of correlations between terrestrial planet mass, disk mass, and the mass of the parent star. We assume that the protoplanetary disk mass scales with stellar mass... Our results suggest that the fraction of systems with sufficient disk mass to form >0.3 Earth mass habitable planets decreases for low-mass stars for every realistic combination of parameters. This 'habitable fraction' is small for stellar masses below a mass in the interval 0.5 to 0.8 Solar masses [which] excludes most M stars. Radial mixing and therefore water delivery are inefficient in lower-mass disks commonly found around low-mass stars, such that terrestrial planets in the habitable zones of most low-mass stars are likely to be small and dry." - Note: For comparison, Mars has 0.107 Earth mass.
- "Emission Line Variability of the Accreting Young Brown Dwarf 2MASSW J1207334-393254: From Hours to Years" by Stelzer, Beate with Alexander Scholz & Ray Jayawardhana, abstract & PDF at arXiv.org 13 July - Quote: "[We] confirm that the accretion rate of 2M1207 varies by more than one order of magnitude on timescales of months to years... Despite the obvious presence of a magnetic field, no radio nor X-ray emission has been reported for 2M1207. Possibly strong accretion suppresses magnetic activity in brown dwarfs, similar to the findings for higher mass T Tauri stars."
NEOCP Activity on 13 July '07
The MPC's NEO Confirmation Page has 2 listings: 2 updated
When last checked at 2301 UTC today, the Minor Planet Center's NEO discovery Confirmation Page (NEOCP) had two updated listings. Of these, none were "one nighters." Major News counted a total of three objects listed on the NEOCP at some point on this day.
