On February 11 at 18:00, Sergey Popov will come to the PostNauka Control Room. We will talk with him about the formation of neutron stars, how neutron stars and black holes are similar, and where did the giant magnetic field and density come from? The broadcast will be hosted by PostNauka co-founder Roman Avdeev and PostNauka researcher Ilya Gridnev. Sergey Popov is a doctor of physical and mathematical sciences, professor of the Russian Academy of Sciences, and leading researcher at the Sternberg Astronomical Institute of Moscow State University. 00:00 Introduction 01:29 What are neutron stars (NS)? 04:01 Why study NS? 07:27 How are NS different from other stars? 08:58 How do NSs form? 11:24 What does the outcome of a supernova explosion depend on? 14:13 Are we sure that the physics we know works in NSs? 18:50 How were NSs predicted and discovered? 23:00 How many NSs have been discovered so far? 24:21 How rare are NSs? 27:13 How are NSs studied? What parameters are measured? 31:49 Why do NSs rotate so fast? 38:43 How does the temperature of NSs change? 42:42 Can NSs cool down completely? 44:45 Why do NSs have such high speeds? 47:52 Are NSs in binary systems rare? 51:07 How can NSs be accelerated to fractions of the speed of light? 54:41 Cartoon: How do stars die? 57:55 Evolution of NSs. What types of NSs are there? 1:01:42 How do NSs transform from one type to another? 1:04:22 How do we know how NSs evolve? 1:09:22 Is the process of NSs birth the same? 1:12:11 Do unusual NSs form in binary systems? 1:15:30 How do neutron stars die? 1:19:19 What does neutron star consist of? 1:27:00 What is in the depths of neutron stars? 1:32:22 Is it possible to model the depths of neutron stars? 1:37:51 When will we know exactly what is in the depths of neutron stars? 1:44:07 What are fast radio bursts? 1:52:00 Latest discoveries in the field of neutron stars 1:55:50 Questions from listeners Sergei Popov's course "Neutron stars and black holes": https://postnauka.ru/courses/17745 Support PostNauka — https://postnauka.ru/donate/ More lectures, interviews and articles about fundamental science and the scientists who create it, see the website http://postnauka.ru/.
