Description
We study the structural properties of the low surface brightness stellar hosts in blue compact galaxies by fitting a two-dimensional Sérsic law to their optical images. The accurate isolation of the starburst emission is an important strength of the method. It allows us to obtain more reliable structural parameters, especially when a Sérsic law is fitted. Preliminary results on the structural properties of the host galaxy for a sample of 28 blue compact galaxies are presented here. Correlations between galaxy and starburst sizes, luminosities, central surface brightnesses, colors and the Sérsic index n, as well as with the neutral hydrogen mass and line width, W20, are studied. Furthermore, we compare the structural properties of the sample with those of other types of dwarf galaxies in order to shed some light on possible evolutionary connections.

Starsbursts play a key role in the cosmic evolution of galaxies, and thus in the star formation (SF) history of the universe, the production of metals, and the feedback coupling galaxies with the cosmic web. Extreme SF conditions prevail early on during the formation of the first stars and galaxies, therefore, the starburst phenomenon constitutes a

    Kaon physics is at a turning point - while the rare-kaon experiments NA62 and KOTO are in full swing, the end of their lifetime is approaching and the future experimental landscape needs to be defined. With HIKE, KOTO-II and LHCb-Phase-II on the table and under scrutiny, it is a very good moment in time to take stock and contemplate about the

    Nodal Precession of a Hot Jupiter Transiting the Edge of a Late A-Type Star TOI-1518

    TOI-1518b, a hot Jupiter around a late A-type star, is one of the few planetary systems that transit the edge of the stellar surface (the impact parameter b~0.9) among hot Jupiters around hot stars (Cabot et al. 2021). The host star's high rotation speed (Vsini s~85 km s -1) and the planet's nearly polar orbit (λ~120 deg) may cause a nodal
