|---|---|
| Discovery | eRASSU J0608-704014 (eRASSU J0608), an ultracompact double white dwarf binary, was identified by an Indian-led international team. |
| Key Finding | The orbit is decaying rapidly at 4.7 × 10⁻¹¹ seconds per second, attributed to gravitational wave emission. |
| Observations | Monitored for 3.5 years using NASA's NICER, China's Einstein Probe, and ESA's XMM-Newton. |
| Gravitational Waves | A potential verification source for future detectors like LISA (Laser Interferometer Space Antenna, ESA, planned launch 2035). |
