unveiLing the populAtion of cloSe-in exoplaneTs and brOwn dwaRf companIons to stArs
LASTORIA is the postdoc project led by Ján Šubjak in collaboration with The Center for Astrophysics | Harvard & Smithsonian, the Czech Academy of Sciences and the KESPRINT consortium.
The project's main goal is to determine the population of close-in exoplanets and brown dwarfs across stars of different spectral types focusing especially on the populations around intermediate-mass stars (F-type and A-type stars), which remain relatively unexplored because of their specific characteristics that make radial velocity measurements more difficult. These systems are crucial to understanding the impact of stellar properties on the formation and evolution of substellar objects.
We plan to approach this goal in three different ways:
Expand the population of transiting BDs and then use the population to study its demographics.
Contribute to the long-term goal of the KESPRINT consortium, which is to study the demographics of small terrestrial planets.
Study the frequency of substellar objects around Am stars to understand the nature of the Am phenomenon.
