Announcing the 18th Marc Aaronson Memorial Lecturer

The Aaronson Committee has met, and it's our pleasure to announce that our 18th Marc Aaronson Memorial Lecturer is Vasily Belokurov of the Institute of Astronomy, in Cambridge, UK. Buell Jannuzi has telephoned Dr. Belokurov, and Dr. Belokurov has accepted with great pleasure. We are shooting for a Fall 2015 talk.

Dr. Belokurov is cited for his long-term work on discovery of Milky Way dwarf galaxies, on being astronomy's premier data miner, for his work on star streams culminating in the Field of Streams, for his work (with students) on the structure and size and density distribution of the Milky Way from BHB stars, on discovering gravitational lenses in the Cassowary Survey, and on data mining to discover metal-poor dIrr galaxies from SDSS imaging (with MMT followup). To put things in perspective, of the sixteen or so ultra-faint galaxies orbiting the Milky Way, Dr. Belokurov has been on the discovery papers of ~10 (mostly as first or second author).

You can learn more about this award in the paragraph below and at http://en.wikipedia.org/wiki/Marc_Aaronson_Memorial_Lectureship

The Marc Aaronson Memorial Lectureship was established to honor our Steward Observatory colleague who died tragically in 1987 at the age of 36. In his spirit, we honor an individual, within 15 years of the PhD, who by his or her passion for research and dedication to excellence, during the ten years preceding the award, has produced a body of work in observational astronomy which has resulted in a significant deepening of our understanding of the universe." [Since Marc was 10 years past his PhD at his death and had already been on the cover of Time Magazine, a few years ago we changed the rules to guarantee a younger person.]

Got Planets? Smaller Stars Are The Best Bet

A group of scientists, Daniel Apai of Steward Observatory and Gijs Mulders and Ilaria Pascucci of UA Planetary Sciences, have continued the quest for Earth-size planets. They have shown that lower-mass stars make for more promising hunting grounds than do their sun-like counterparts. Stars weighing in at less than half of the sun's mass are twice as likely to possess Earth to Neptune-sized planets and these planets can be found closer to their host stars, the research team reports in the Astrophysical Journal. The study suggests that scientists looking for planets outside of our solar system are more likely to discover Earth-size planets by focusing their search on lower-mass stars. The UA press release can be found HERE. The preprint of the now-published article can be found HERE.

Two former Stewardites, Charles Liu (PhD 1996) and Sally Oey (PhD 1995), and current NOAO staff member Knut Olsen, were elected to American Astronomical Society positions: Sally is a Councilor, Charles is Education Officer, and Knut is on the Nominating Committee. For more information, see HERE.

THIS article contains a variety of thoughts by Chris Impey on how one might fund a serious mission to Europa. The obvious way, proposing to NASA, is underway, and some LPL folks discuss the new call for proposals HERE. The spaceflightinsider article linked above contains some other thoughts and ideas, namely, private funding.

Chris Impey's next Massive Online Open Course is set to begin Feb 15. An article and a Q&A with Chris can be found HERE. While Chris's first MOOC continues, this one has tweaks, such as more videos, quizzes, outside activities and peer-reviewed writing. There are two overarching goals: the first is to teach astronomy to those signed up and have them come away with knowledge and ideas of the richness of what we study; the second is to learn how to do a better job teaching these sorts of very different classes. You can also check out this video link from Chris's Facebook page HERE. The website for the course is HERE, and the Coursera link is HERE. Finally, a recent radio interview with Chris can be found HERE

"Lo Que Pasa" recently interviewed University Distinguished Outreach Professor, Dr Don McCarthy of Steward Observatory. This series of interviews asked recently honored professors why they're at the UA. There's a four-minute video HERE. Don is well known for more than two decades of running Astronomy Camp using local telescopes (LINK), and for his presence in the introductory (Gen Ed) classroom and young astronomy majors classroom, and as a faculty fellow in Coconino Hall.

UA News recently reported HERE on a visit by a Mexican Science Delegation. Steward is collaborating on a 6.5m telescope for San Pedro Martir, Baja, Mexico. One possible plan is for that new telescope and the MMT to coordinate/share instruments. An old UANews article can be found HERE.
