Title: Tidal Dissipations in Binaries: From Merging White Dwarfs to and Hot Jupiter Systems

Speaker:Dong Lai(Cornell University)

Time:Friday, 3:00pm,19th July

Location:Middle Conference Room, 3rd floor

　　Dynamical tides, involving the excitation and dissipation of waves and oscillation modes, play an important role in many different binary systems. I will discuss recent works on dynamical tides in three types of systems: (i) Compact white dwarf binaries undergoing orbital decay due to gravitational radiation; (ii) main-sequence star binary exhibiting tidally induced oscillations; (iii) Exoplanetary systems containing hot Jupiters and misaligned host stars.
