Tuesday November 12:

Seminar talk with Driss Takir, Postdoctoral Teaching Fellow, Department of Physics, Ithaca College

Title: Spectroscopy of Outer Main Belt Asteroids and Carbonaceous Chondrites.

Abstract: The carbonaceous chondrite meteorites I study are primitive meteorites that consist of some of the most pristine matter known in the Solar System, unaltered since the original condensation from the solar nebula. These meteorites have been shown to contain amino acids that are the precursor molecules to life. Some of these meteorites even contain diamonds from a highly energetic event- possibly from a supernova that occurred before the formation of our solar system's nebula. These carbon-rich meteorites are relatively rare in our earthly collections and are thought to come from primitive asteroids that orbit the Sun between 2.5 < a < 4.0 AU (between Mars and Jupiter). They are also thought to be the source of water and organics delivered to terrestrial planets during their formation. In this talk I will discuss how I developed reliable spectral signatures that can place constraints on the degree and location of thermal energy deposited in these meteorites that may have aqueously altered the minerals. Using the SpeX spectrograph/imager at NASA Infrared Telescope Facility (IRTF), I measured near-infrared (NIR: 0.7-4.0 micron) spectra of 45 outer Main Belt asteroids  and I used the JHU APL lab spectrometer to measure 10 meteorite spectra that allowed the identification of four  spectral groups, each of which reflects a distinct surface mineralogy AND THESE GROUPS HELP US TO UNDERSTAND THE DIVERSITY OF THERMAL HISTORIES IN THE ASTEROID REGIONS - POINTING THE WAY TO A BETTER UNDERSTANDING OF SOLAR SYSTEM FORMATION ENERGETICS.

12:10 P.M. in CNS 206B
Pizza and refreshments provided for $1. Please bring your own cup. Remember to Reuse, Reduce, Recycle.

Friday November 15:

Join us for Public Viewing night, Friday, November 15th from 8:00 p.m. to 10:00 p.m.

You are invited to join the Ithaca College Department of Physics for a Public Viewing of the night sky at the Clinton B. Ford Observatory on Friday,  November 15th from 8:00 p.m. to 10:00 p.m.

To attend a Public Night
Just show up the vehicle 'turn around' in front of the entrances of Smiddy Hall and CHS (F lot side). A shuttle van will make regular runs to convey people up to the observatory and back down. Please note that there is NO parking available up at the observatory and that the access road is NOT lighted. For your own safety, please do not walk up.

Bad Weather Plan
The "go/no-go" decision for any public night will be made at 3:30 pm on the scheduled date. Our web page and the recorded message at the observatory will be updated shortly thereafter to reflect the decision for that evening. So if you check our website or call the observatory at 607-274-3012 after 4:00 pm you will get the final decision for that evening.
