Briefings
Researchers detected TOI-2535b, a hot Jupiter transiting its host star TOI-2535 for seven years, but it ceased showing up recently. This disappearance suggests an unseen companion planet orbiting in a different plane, potentially blocking the light. The timing of the transit is now irregular, which could indicate gravitational perturbations from the new body. The discovery highlights how exoplanet timing can reveal hidden companions, though the exact cause remains unconfirmed.
Key points
- TOI-2535b is a hot Jupiter-sized planet transiting its host star TOI-2535 for approximately seven years.
- The planet's transit timing has recently ceased, suggesting an unseen companion in a different orbital plane.
Context
Exoplanet transit timing is used to detect gravitational influences from additional planets in the same system. TOI-2535b's disappearance marks a significant shift in its observed behavior, potentially indicating a new gravitational source.
Limitations
The evidence is limited to a single article report from November 2026. The specific date of the disappearance is not provided, and the exact nature of the unseen companion remains unconfirmed. No additional background on the host star or system is supplied.
