Stellar Pulsation: Challenges for Theory and Observation
Santa Fe, New Mexico
May 31 - June 5, 2009
Conference Program
Talks
The detailed program of oral presentations is now available for download as a pdf by clicking here. All talks will be held in the ballroom on the second floor of the La Fonda hotel. The schedule is also visible at the bottom of this page. Invited review talks will be 30 minutes including question and answer time. Contributed talks will be 15 minutes including question and answer time. The screen size on which talks will be projected is 10 feet x 10 feet.
The conference talks will run through Friday afternoon at 4 pm, so please plan to stay the entire week.
Posters and poster size
A list of poster titles and presenting authors is available by pdf by clicking here. Because we have received over 80 submissions, to comfortably fit into the poster space we have divided the posters into two sessions, Sun-Mon-Tues and Wed-Fri. In addition to breakfast, coffee breaks, and lunch breaks, there are two dedicated poster viewing times, one for each session, 10:30-noon Tuesday and 10:30-noon Thursday.
The first session poster boards will be ready for setup in Ballroom North as early as 4:00 pm Sunday May 31 (before the reception). The posters for the second session can remain up until the end of the conference at 4:00 pm Friday June 5.
Posters will be attached to the backing with Velcro, which will be available. The available space is 46 7/8" (inches) wide by 36 9/16" (inches) tall, not including an optional header board area available for a title. A diagram of the poster backing is available here.
Abstract Book
We are now printing the abstract book for the conference. You may download a pdf of the abstract book by clicking here (3.1 Megabytes). A printed double-sided copy of the abstract book with spiral binding will be included in your registration packet.
Special events
The reception (Sunday evening, May 31) and the banquet (Thursday evening, June 4) will be held at La Terraza, which is on the third floor of the La Fonda hotel starting at 6 pm. Light refreshments will be provided every morning and afternoon outside of the ballroom. Conference participants are on their own for lunch—please consult Salman Habib's restaurant listing or ask one of the conference organizers for lunch suggestions.
Wednesday afternoon there will be a tour of Los Alamos and surrounding attractions provided by Buffalo Tours—the bus will leave the La Fonda Hotel at 13:30 and return at 19:00. Cost for the tour is $46 (not included in registration). Please see the Tours page for additional information and other available companion tours.
At the banquet Thursday, June 4, we will have a special guest speaker Robert Christy (link to biography and photo) who is now 93 years old and a Professor Emeritus at Caltech. Dr. Christy attended the first Los Alamos Stellar Pulsation Conference in 1971.
We will also have special music at the banquet, the Mozart Clarinet Quintet, performed by Bob Chrien, Jim Knudson, Alice Mutschlechner, Rachel Hixson, and Carol Nielson of Los Alamos.
