Article Synopsis
- Planets form in dust and gas disks around stars and can collide after the gas dissipates, causing changes in mid-infrared emissions from stars.
- Monitoring with the warm Spitzer mission detected significant infrared brightening from the star ASASSN-21qj, linked to a collision between exoplanets, with a noted brightening at around 1,000 Kelvin lasting for about 1,000 days.
- The observed optical eclipse occurred 2.5 years after the infrared change, suggesting a longer orbital period and indicating that the collision created debris affecting the star's visibility.
