Polluted White Dwarfs
Time: 2:30 p.m.
Location: Geology 3656
Lecture by Prof. Ed Young

When a star the size of the Sun has burned all its H and He, it starts to cool by radiation. It eventually becomes very dense; white dwarfs typically contain the mass of the Sun in an Earth-size star. The gravitational field is so strong that elements other than H and He settle out of the atmosphere on a short time scale (months to 106 years). Thus it was a surprise when detailed surveys showed 25% of white dwarfs to be polluted with asteroidal or cometary debris. Recent studies of WD atmospheres thus allow comparison of these pollutants with the smaller materials orbiting our Sun.

Death Valley National Park Fossil Thieves

$1,000 Reward – Death Valley National Park

Fossil Thieves stole several fossilized footprints, which had been left in a lakebed by mammals and birds, were missing. Now, Ryan F. Mandelbaum reports for Gizmodo, the National Park Service is asking for the public’s help in identifying a group of backpackers who may have information on the ancient tracks.  In a statement, the National Park Service released the photos of three men who might have witnessed the crime or have knowledge about the disappearance of the footprints. Investigators are offering an award of up to $1000 “for information leading to the identification, arrest, and conviction of those responsible,” the statement reads. According to Mandelbaum, investigators are planning to interview visitors who frequented the Park at the time of theft, in the hopes that someone will be able to provide valuable clues.

Destroying—or pilfering—the property of national parks is prohibited by law. “It’s illegal to collect fossils, rocks, or anything else in National Parks,” Park Superintendent Mike Reynolds said in a statement about the fossil thefts. “The purpose of National Parks is to conserve the landscape and everything it contains for the next generation. I ask that visitors come and enjoy all there is to see, and to leave it unimpaired for others to enjoy.”

The National Park Service has asked anyone with information about the stolen fossils to call the Investigative Services Branch at 1-888-653-0009.
