REPEATING STELLAR JETS

A group research project for PY 228 students.

We will explore the hypothesis of Bally & Devine (Astrophysical Journal, 428, L65) that the apparent linear string of Herbig-Haro objects in Orion are the consequence of a quasi-periodic, collimated outflow originating from the young stellar object known as HH 34*. We will investigate the dynamics and appearance of such a repeating stellar jet using hydrodynamical simulations performed on the Cray Y/MP at the North Carolina Supercomputing Center.

This project is broken down into 5 different task groups:

Background Research
Theoretical Model
Numerical Model
Visualization and Data Analysis
Dissemination of Results

A Bibliography of recent research on Herbig-Haro Objects and Stellar Jets.
