Axisymmetric second order perturbations of rotating main sequence stars
Umin Lee
We calculate the second order perturbations driven by oscillation modes of rotating stars. Assuming that the typical amplitude of oscillation modes is small, we expand the pert…
HD 42477: coupled r modes, g modes and a p mode in an A0Vnne star
D. W. Kurtz, R. Jayaraman, P. Sowicka +4
Several studies have shown that a number of stars pulsating in p modes lie between the Cep and Sct instability strips in the Hertzsprung-Russell (HR) Diagram. At present, t…
Non-linear excitation of low frequency modes by overstable convective modes in rotating stars
Umin Lee
We discuss non-linear excitation and amplitude saturation of -modes, -modes and overstable convective (OsC) modes in early type main sequence stars, taking account of the eff…
Overstable Convective Modes in Rotating Early Type Stars
Umin Lee
We calculate overstable convective (OsC) modes of , , and main sequence stars. To compute non-adiabatic OsC modes in the core, we assume $(\nabla\cd…
Rotation of the convective core in Dor stars measured by dips in period spacings of g modes coupled with inertial modes
Hideyuki Saio, Masao Takata, Umin Lee +2
The relation of period spacing () versus period () of dipole prograde g modes is known to be useful to measure rotation rates in the g-mode cavity of rapidly rotating Do…
Transport of angular momentum by stochastically excited waves as an explanation for the outburst of the rapidly rotating Be star HD49330
C. Neiner, U. Lee, S. Mathis +3
HD49330 is a Be star that underwent an outburst during its five-month observation with the CoRoT satellite. An analysis of its light curve revealed several independent p and g puls…
