Understanding of phenomena that we thought we already knew, andĮnabled the first insights into the physics of neutron star mergers This effort has led to theĭiscovery of new types of astronomical transients, revolutionized our Sky with unprecedented temporal cadence and sensitivity across theĮlectromagnetic spectrum and beyond. New and improved observational facilities we can now sample the night Including the most extreme stellar deaths, stellar tidal disruptionsīy supermassive black holes, and mergers of compact objects. Title: "The Renaissance of Astrophysics: a landscape of opportunities in the era of Time Domain Multi-Messenger investigations"Īstronomical transients are signposts of catastrophic events in space, Raffaella Margutti (Northwestern University) Parameters, we can reproduce the relative frequency of super-Earth and Ideas to demonstrate that for a reasonable distribution of disk Systems, yielding a population of gas giants that well matches theĭata and in particular explaining why higher-mass giants are more If multiple gas giants are instead produced in inner planetary Will then discuss how a giant impact phase for giant planets results I will present work showing that flow isolationĬan yield systems of super-Earths comparable to those observed. The thermal mass, comparable to the distinct “pebble isolation mass.”Īt larger orbital separations or if Stokes numbers are smaller, these One, then flow isolation yields limiting masses similar in scale to If fragmentation limits “pebble” sizes to Stokes numbers approaching Sizes present in the planet’s natal disk. Its consequences are highly dependent on the particle Flow isolation occurs when small particles,Ĭoupled to the gas, are pulled around a growing planet along gas Questions that appeals to the “flow isolation mass,” a limiting massįor pebble accretion.
