Variations in exoplanet timing can reveal gravitational influences from additional planets in the same system, while precise timing can help researchers point telescopes at a system when light has passed through a planet’s atmosphere.
Exoplanet TOI-2535b stops showing up after about seven years
Researchers report disappearance, suspect unseen companion
Researchers reported on Monday that an exoplanet, TOI-2535b, which had been transiting its host star TOI-2535 for about seven years, has stopped appearing in observations. The hot Jupiter-sized planet's disappearance is suspected to be due to an unseen companion orbiting in a different plane.

Analysis
Why This Matters
- The sudden disappearance of a regularly transiting exoplanet challenges assumptions about orbital stability and consistency.
- It suggests the presence of hidden objects in exosolar systems that can influence planetary orbits.
- Long-term observation programs remain crucial for detecting such unexpected changes in distant planetary systems.
Background
Exoplanets are often discovered through their transits, or passages in front of their host stars, which occur predictably. The timing of these transits can reveal variations caused by the gravitational pull of other planets in the system. In the case of TOI-2535b, a hot Jupiter-sized planet, its transits had been observed for about seven years before it stopped showing up.
What to Watch
- Further observations to confirm the presence and nature of the suspected unseen companion.
- Potential detection of similar disappearing exoplanets in other systems.
