    Phosphine (PH3) has emerged as a potential biosignature gas, particularly in high-pressure, CO2-dominated exoplanetary atmospheres analogous to Venus. This research explores the feasibility of detecting trace amounts of phosphine using simulated transmission spectra from petitRADTRANS (pRT). The central research question investigates how varying phosphine mixing ratios influence the...

    Talk

    The TOI-201 system, featuring a young F-type star approximately 870 million years old, has emerged as one of the most intriguing planetary laboratories discovered so far. Our recent studies have unveiled a remarkable planetary architecture, including the detection of TOI-201 c - an additional massive gas giant with a 7.7-year orbital period. This discovery was facilitated by the analysis of...

    Talk

    Understanding star and planet formation in extreme environments is crucial for uncovering the origins of our solar system. While most knowledge comes from nearby, isolated regions such as Taurus and Lupus, over half of all stars and planetary systems form in environments exposed to strong far-ultraviolet (FUV) radiation, emitted by massive OB stars, with energies below the Lyman limit (E <...
