The next Colloquium of the Astronomical Observatory will be held on Wednesday, April 1, at 12 PM in the Library.
Speaker: Prof. Dr. Sergei B. Popov from the Sternberg Astronomical Institute, Moscow State University, in Russia.
Topic: Long-period radio transients
Resume: A few years ago, a new class of astronomical sources was identified: long-period radio transients. These sources are characterized by spin periods from several minutes up to several hours. Mostly, their nature remains uncertain. Most probably, there are two types of objects: compact white dwarf binaries with red dwarf companions and highly magnetized isolated neutron stars. I n the talk, I discuss both approaches, review the present-day observational data, and present some of our results (including work in progress). In the framework of the evolution of isolated neutron stars, we discuss the origin and the fate of long-period radio transients (arXiv: 2309.12080). Also, I present our detection of a radio burst from a white dwarf low-mass binary, which can be similar to the activity of long-period radio transients.
