The Astronomical Journal, 2023 We study the emergent spectral fluxes of transiting hot Jupiters, using secondary eclipses from Spitzer. To achieve a large and uniform sample, we have reanalyzed all secondary eclipses for all hot Jupiters observed by Spitzer at 3.6 and/or 4.5 μ m.

First results of the Kourovka Planet Search: discovery of transiting exoplanet candidates in the first three target fields [PDF]
, 2016 We present the first results of our search for transiting exoplanet candidates as part of the Kourovka Planet Search (KPS) project. The primary objective of the project is to search for new hot Jupiters which transit their host stars, mainly in the ...

deep PACO: Combining statistical models with deep learning for exoplanet detection and characterization in direct imaging at high contrast [PDF]
Monthly notices of the Royal Astronomical Society, 2023 Direct imaging is an active research topic in astronomy for the detection and the characterization of young sub-stellar objects. The very high contrast between the host star and its companions makes the observations particularly challenging.
