At the heart of many large galaxies, a supermassive CN22 model, which determines the peak timescale for TDEs as a function of the properties of the star and the mass of the black hole. From this new model, they recovered TDE peak timescales and accretion rates that agreed with the results of some hydrodynamical simulations, but the broader implications of this model – and also its predictions over a wider range of stellar type, including the mass and age of the star – were not completely elucidated.
To better characterize and understand the predictions of this model in a wider context, a team of researchers from Syracuse University, led by Ananya Bandopadhyay, a Ph.D. student in the Department of Physics, conducted a study to analyze the implications of the CN22 model and test it against different types of stars and SMBHs of various masses. The team’s work has been published in DOI: 10.3847/2041-8213/ad0388
