Tidally excited gravity waves in the cores of solar-type stars: resonances and critical-layer formation
Zhao Guo, Gordon I. Ogilvie, Adrian J. Barker
We simulate the propagation and dissipation of tidally induced nonlinear gravity waves in the cores of solar-type stars. We perform hydrodynamical simulations of a previously devel…
Impact of Correlated Noise on the Mass Precision of Earth-analog Planets in Radial Velocity Surveys
Jacob K. Luhn, Eric B. Ford, Zhao Guo +6
Characterizing the masses and orbits of near-Earth-mass planets is crucial for interpreting observations from future direct imaging missions (e.g., HabEx, LUVOIR). Therefore, the E…
Modeling Stellar Oscillations and Granulation in Radial Velocity Time Series: A Fourier-based Method
Zhao Guo, Eric B. Ford, Dennis Stello +4
Tens of thousands of solar-like oscillating stars have been observed by space missions. Their photometric variability in the Fourier domain can be parameterized by a sum of two sup…
A New Window to Tidal Asteroseismology: Non-linearly Excited Stellar Eigenmodes and the Period Spacing Pattern in KOI-54
Zhao Guo, Gordon I. Ogilvie, Gang Li +2
We revisit the Tidally Excited Oscillations (TEOs) in the A-type, main-sequence, eccentric binary KOI-54, the prototype of heartbeat stars. Although the linear tidal response of th…
