The discovery of transiting planets with orbital periods exceeding 40 days has been exceptionally rare among the 5000+ planets identified to date. This dearth of findings poses a significant challenge to studying planetary demographics, formation, and evolution. In this study, we report detecting and characterizing HD88986 b, a potentially transiting sub-Neptune with the longest orbital period...
The Galaxy has an extremely large number of free-floating planets (ffps), either being bound in star clusters or orbiting freely around the Galaxy. The presence of these objects is common in all large scale objects, whatever we consider brown dwarfs as ffp or not. In my work, I will explain how these objects, with different abundances, remain gravitationally bound or are ejected from star...
Microlensing observations suggest that the mass distribution of free-floating planets (FFPs) follows a declining power-law with increasing mass. The origin of such distribution is unclear. Using apopulation synthesis framework, we investigate the formation channel and properties of FFPs, andcompare the predicted mass function with observations. Assuming FFPs originate from...
Cosmochemical studies have proposed that Earth accreted roughly 5%–10% of its mass from carbonaceous (CC) material, with a large fraction delivered late via its final impactor, Theia (the Moon-forming impactor). Here, we evaluate this idea using dynamical simulations of terrestrial planet formation, starting from a standard setup with a population of planetary embryos and planetesimals laid...
