Solar-Like Oscillations: Lessons Learned & First Results from TESS
英文摘要：
Solar-like oscillations are excited in cool stars with convective envelopes and provide a powerful tool to constrain fundamental stellar properties and interior physics. We provide a brief history of the detection of solar-like oscillations, focusing in particular on the space-based photometry revolution started by the CoRoT and Kepler Missions. We then discuss some of the lessons learned from these missions, and highlight the continued importance of smaller space telescopes such as BRITE constellation to characterize very bright stars with independent observational constraints. As an example, we use BRITE observations to measure a tentative surface rotation period of 28.3+/-0.5 days for alpha Cen A, which has so far been poorly constrained. We also discuss the expected yields of solar-like oscillators from the TESS Mission, demonstrating that TESS will complement Kepler by discovering oscillations in a large number of nearby subgiants, and present first detections of oscillations in TESS exoplanet host stars.
