 "The Evolution of Planetary Landscapes from Callisto to Helene"
by Orkan M. Umurhan


Landform evolution modelling has become an important tool in interpreting the landscapes of the icy satellites of the solar system.  In this talk, I will discuss the methods that are applied to this purpose and describe its application to several interesting icy satellite bodies, including Titan, Triton, Callisto and Helene.  The talk will conclude with a preview of landform evolution modelling results applied to Pluto.

Dr. Umurhan’s research focuses on evolutionary processes both on planetary surfaces and in protoplanetary disks. He has published on a number of topics including astrophysical flows and turbulence, fundamentals of shear flow instabilities, geomorphology and landform evolution and its modelling. Dr. Umurhan joined the New Horizons Geology and Geophysics Investigation Team in June of 2013. His main role on this mission has been in providing mathematical modelling framework for the various geophysical scenarios of interest and appropriate to the Pluto system.  Dr. Umurhan regularly writes blogposts for NASA about New Horizons and he is also a co-author on a graduate level textbook on fluid dynamics for physicists due to come out this spring.


Next speaker:  TBA

Bring $3 for a parking permit



The Peninsula Astronomical Society is a group of some 200 Bay Area astronomy enthusiasts of all ages and backgrounds. Some members are professionally trained in astronomy, others are just starting and have never looked through a telescope before. One thing that we all have in common is an interest in the sky.

The PAS holds meetings on the second Friday of each month at 7:30 pm on the campus of Foothill College in Los Altos Hills, CA (between San Jose and Palo Alto).  The meetings are usually held in Room 5015, next to Parking Lot 5 (see map). Each meeting features a speaker (or speakers) bringing us up to date on different topics in astronomy. The public is welcome to attend these meetings; there is no charge to attend.  Note, however, that there is a $3 charge for parking - visitor parking permits are available from the machines in the parking lots.  Please do not park in spaces marked "Staff" - you will be ticketed!

As part of its commitment to bringing astronomy to the public, the Peninsula Astronomical Society operates the Foothill College Observatory (click here for more information). The Observatory is staffed by members of the society who volunteer to conduct the regularly scheduled public programs.

In addition to operating the Foothill Observatory, the PAS has its own observatory in the nearby Santa Cruz Mountains. This location has AC power and room for members to set up their own telescopes at our monthly star parties. This site is also the home of the society's 12" telescope, available for member use after a checkout.
