Global asteroseismology of 19,000 red giants in the TESS Continuous Viewing Zones
K. R. Sreenivas, Timothy R. Bedding, Daniel Huber +5
TESS (Transiting Exoplanet Survey Satellite) has produced long-term photometry for millions of stars across the sky. In this work, we present an asteroseismic catalogue of 19,151 r…
Asteroseismic Diagnostics for Red Giants with Kepler: Measuring epsilon and Small Frequency Separations in 16,000 Stars
Yingxiang Wang, Timothy R. Bedding, Yaguang Li +4
Asteroseismic studies of red giants have primarily relied on two global parameters: the large frequency separation (Dnu) and the frequency of maximum power (numax). Meanwhile, the…
Testing the wavelength dependence of oscillations and granulation in red giants using Kepler and TESS
K. R. Sreenivas, Timothy R. Bedding, Daniel Huber +5
Stellar oscillations and granulation in red giants are both powered by convection. Studying the wavelength dependence of their amplitudes can provide useful insights on the driving…
Realistic Uncertainties for Fundamental Properties of Asteroseismic Red Giants and the Interplay Between Mixing Length, Metallicity and
Yaguang Li, Timothy R. Bedding, Daniel Huber +8
Asteroseismic modelling is a powerful way to derive stellar properties. However, the derived quantities are limited by built-in assumptions used in stellar models. This work presen…
The highest mass Kepler red giants -- I. Global asteroseismic parameters of 48 stars
Courtney L. Crawford, Timothy R. Bedding, Yaguang Li +6
When low- and intermediate-mass stars evolve off the main sequence, they expand and cool into the red giant stages of evolution, which include those associated with shell H burning…
A simple method to measure numax for asteroseismology: application to 16,000 oscillating Kepler red giants
K. R. Sreenivas, Timothy R. Bedding, Yaguang Li +4
The importance of numax (the frequency of maximum oscillation power) for asteroseismology has been demonstrated widely in the previous decade, especially for red giants. With the l…
Asteroseismology of the young open cluster NGC 2516 I: Photometric and spectroscopic observations
Gang Li, Conny Aerts, Timothy R. Bedding +8
Asteroseismic modelling of isolated star presents significant challenges due to the difficulty in accurately determining stellar parameters, particularly the stellar age. These cha…
