Observations with Spitzer telescope show there is likely no atmosphere on nearby exoplanet LHS 3844b

Exoplanet LHS 3844b was discovered in 2018 by space telescope TESS in distance of 49 light-years. Follow-up observations with infrared telescope Spitzer show, that there is likely no atmosphere present due to the proximity to its star LHS 3844.

The exoplanet orbits very close to its star and is likely tidaly locked, meaning one of its hemisphere is always shown to the star. However Spitzer telescope did not detect any heat exchange between the two hemispheres, which would mean presence of atmoshpere with strong winds.
