Further observations and analysis are required to confirm the nature of the system and to verify the planetary candidate.
Determined transits
  • 2461154.51387 (4/24/2026, 00:19)
    Planet designation: TOI-3908 .01
    HJDmid: 2461154.51714 +/- 0.00077
    Heliocentric correction: 0.00327
    Transit depth (Mag): 0.02914 +/- 0.00144
    Transit duration (Min): 110.82 +/- 3.09
    Standard deviation (mmag): 3.08
    Data quality index: 2
    Data density (data/min): 0.41
    Fitting algorithm: Original ETD  
    Note:
    Data reduction and analysis were performed using the HOPS software.
    
    The resulting light curve differs significantly from what is expected for a typical exoplanet transit. In particular, the shape of the signal appears more consistent with that of an eclipsing binary star rather than a planetary transit.
    
    Further observations and analysis are therefore required to confirm the nature of the system and to verify the planetary candidate.
