ASU Prof Gets Grant for Astrophysics Research

Dr. Kenneth Carrell, an assistant professor of physics at Angelo State University, has been awarded a two-year, $105,535 grant from the National Science Foundation (NSF) to fund an astrophysics research project that will also involve ASU undergraduate students.

Also director of the ASU Planetarium, Carrell was awarded the grant through the NSF's new Launching Early-Career Academic Pathways in the Mathematical and Physical Sciences (LEAPS-MPS) program for his project titled "LEAPS-MPS: A Systematic Investigation of Transient Behavior in RR Lyrae Variable Stars."

According to Carrell, RR Lyrae stars physically change in size over the course of about half a day and have been known as a class of variable stars for over a century. However, modern space-based observations have revealed that these stars are actually more complicated than previously thought.

"The NSF grant will pay for myself and several undergraduate students to travel to the McDonald Observatory near Fort Davis twice a year for the next two years to observe some of these stars with newly discovered strange behavior," Carrell said. "Our goal is to use these follow-up observations to try to understand the physics behind the transient phenomena, and to better understand stellar interiors more generally. It will also fund trips to the national American Astronomical Society meetings so the undergraduate students can present the work."

The NSF's new LEAPS-MPS program is designed to help launch the careers of pre-tenure faculty in mathematical and physical sciences at minority-serving institutions and predominantly undergraduate institutions. The ultimate goal is to increase participation by student populations that are traditionally under-represented in those fields. As such, consideration for grant awards is based on both scientific merit of proposals and the broader impacts on those under-represented groups at the university and in the community.
