[Baps] Spitzer talk on Epsilon Eridani

[Sarah T. Stewart-Mukhopadhyay]

FRIDAY, NOVEMBER 18

12:30 pm: Radio and Geoastronomy Division Lunch Talk
<http://cfa-www.harvard.edu/%7Eehumphre/RGtalks/> . "A Spitzer View of the
Epsilon Eridani Planetary System," Dr. Massimo Marengo, CfA. Room M-340, 160
Concord Avenue. 

Abstract: Epsilon Eridani is a younger, dustier solar system analogous. With
an age of 850 Myr and a spectral type of K2V, it is a young main sequence
star with a mass just below that of the Sun. It harbors a dusty "debris
disk" found by IRAS and first imaged at sub-mm wavelength, roughly the size
of our own Kuiper belt. It is also home of at least one Jupiter-size planet,
found with radial velocity techniques. These characteristics, and the
proximity of epsilon Eridani to the Sun make it the ideal subject to study
what could have been the early history of our own solar system. The Spitzer
Space telescope, with its high sensibility and stability, offers a unique
perspective to complete this picture, at wavelengths where the dust
emissions from the disk are stronger, and it is easier to search for direct
emission from sub-stellar companions.
