Title: [CANCELLED] Recent Updates on Near-Sun Objects

Abstract: Near-Sun objects are a population of small solar system bodies characterised by extremely close distances to the Sun around perihelion within the orbit of Mercury. Their peculiar orbits inevitably pose often insurmountable challenges for discoveries and observations of these objects, hindering attempts to explore them and making them arguably the least studied population of small bodies in the solar system. However, the scarcity of near-Sun objects cannot be fully accounted for by the observational bias but is also suspected to be associated with physical mechanisms leading to their fragmentation that are probably not frequently seen elsewhere in the solar system. In this talk, I will highlight recent progress in studies of near-Sun objects and discuss how these can shed light on the understanding of this population.
