Primary Science
The Rossi Timing X-ray Explorer, or RXTE for short, was designed to study time variability in the emission of X-ray sources over timescales from microseconds to months.
Science Highlights
- Discovered kilohertz quasi-periodic oscillations
- Discovered the spin periods in low-mass X-ray binary systems
- Detected X-ray afterglows of gamma-ray bursts
