Seminars for Scientists

2015 Spring Schedule

This page is for the LASP Science Seminars Spring 2015 Series. See upcoming talks listed below. We still have open slots and are actively recruiting new speakers. If you or a colleague would like to give a seminar this fall, please contact the Seminar Organizer Mikki Osterloo (firstname.lastname at LASP seminars are held every Thursday at 4:00 PM in the SPSC building, generally in room W120. Refreshments are served at 3:45. All LASP science seminars are open to visitors and our colleagues in other departments.

1/15/2015 Seminar – Subsurface Imaging with SHARAD and Implications for the Recent Climate History of Mars

Speaker:   Than Putzig (SwRI)
Date & Time:   01/15 ,  4:00 PM Location: SPSC W120

In the fifty years since the launch of Mariner 4, an armada of missions with progressively more sophisticated instrumentation has transformed our view of Mars, revealing a planet of outsized features with a complex geologic history and extraordinary climatological variations. Despite the wealth of observations, knowledge of the interior has been largely limited to inferences […]

1/16/2015 Seminar – Variational Integrators in Plasma Physics; Sewing the Geometric Fabric of Physics into Numerical Models

Speaker:   C Leland Ellison (Princeton Univ.)
Date & Time:   1/16 ,  1:00 PM Location: SPSC W120

The behavior exhibited by dynamical systems is strongly influenced by the presence or absence of conserved quantities. When numerically modeling these systems, obtaining the correct long-term qualitative behavior requires retaining conservation laws in the numerical update rule. One method for constructing conservative numerical models is to derive the algorithm from a variational principle discretely analogous […]

1/22/2015 Seminar – Chemistry and Spectroscopy of Thermospheric Nitric Oxide and the Legacy of Charles A. Barth

Speaker:   Justin Yonker (NCAR)
Date & Time:   1/22 ,  4:00 PM Location: SPSC W120

Though often considered a minor species, nitric oxide (NO) plays several key roles in the thermosphere.  It terminates the ion-neutral chemistry due to its low ionization potential.  Its long lifetime enables it to be transported to the middle atmosphere where it will catalytically destroy ozone.  And as the primary heteronuclear species, infrared radiation from vibrationally […]

1/29/2015 Seminar- Understanding Electron-Hole Instabilities in the Lunar Plasma Wake

Speaker:   Ian Hutchinson (MIT)
Date & Time:   1/29 ,  4:00 PM Location: SPSC W120

The moon, like many objects in flowing plasma, gives rise to a rarefied quasineutral plasma wake that attracts ions along the magnetic field giving rise to beam-like ion distributions, known theoretically since the 1960s, and observed by satelites. Recent particle in cell simulations of the wake at realistic mass ratio show ion-disrupting instabilities grow in […]

2/5/2015 Seminar- Investigating our Heliospheric Environment: IBEX Observations

Speaker:   Harald Kucharek (Univ. of New Hampshire)
Date & Time:   2/5 ,  4:00 PM Location: SPSC W120

The Interstellar Boundary Explorer (IBEX) launched in Oct. 2008 and the observations by the Voyager spacecraft provided truly remarkable advances in heliospheric research. While Voyager provided in situ measurements of the plasma conditions on leaving our solar system, IBEX imaged the interactions occurring at the boundary of our heliosphere in all directions in space by […]

2/19/2015 Seminar- TBD

Speaker:   Joe Michalski (PSI)
Date & Time:   2/19 ,  4:00 PM Location: SPSC W120


2/26/2015 Seminar – Space Weathering on Volatile-Rich Asteroids; Or How Rocks Can Make Glass, Iron, and Life

Speaker:   Dan Britt (Univ. of Central Florida)
Date & Time:   2/26 ,  4:00 PM Location: SPSC W120

Space weathering refers to the alterations suffered by solid materials when directly exposed (i.e. no atmosphere) to the space environment. The classic example is the weathering of the lunar regolith in which common rock-forming minerals decompose into glassy aggregates with nanophase iron. The lunar nanophase iron produces a characteristic spectral red slope. But how do […]

3/5/2015 Seminar- TBD

Speaker:   Steven Cranmer (LASP)
Date & Time:   3/5 ,  4:00 PM Location: SPSC W120


3/12/2015 Seminar- TBD

Speaker:   Tim Cassidy (LASP)
Date & Time:   3/12 ,  4:00 PM Location: SPSC W120


3/19/2015 Seminar- TBD

Speaker:   Hironobu Iwabuchi (Tohoku Univ.)
Date & Time:   3/19 ,  4:00 PM Location: SPSC W120
