A 20-Second Cadence View of Solar-Type Stars and Their Planets with TESS: Asteroseismology of Solar Analogs and a Re-characterization of pi Men c
Daniel Huber, Timothy R. White, Travis S. Metcalfe +50
We present an analysis of the first 20-second cadence light curves obtained by the TESS space telescope during its extended mission. We find a precision improvement of 20-second da…
Can small-scale magnetic fields be the major cause for the near-surface effect of the solar p-mode frequencies?
Yan Li, Qian-sheng Zhang, Tao Wu +5
Small-scale magnetic fields are not only the fundamental element of the solar magnetism, but also closely related to the structure of the solar atmosphere. The observations have sh…
TESS Asteroseismic Analysis of the Known Exoplanet Host Star HD 222076
Chen Jiang, Timothy R. Bedding, Keivan G. Stassun +24
The Transiting Exoplanet Survey Satellite (TESS) is an all-sky survey mission aiming to search for exoplanets that transit bright stars. The high-quality photometric data of TESS a…
Detection and characterisation of oscillating red giants: first results from the TESS satellite
Víctor Silva Aguirre, Dennis Stello, Amalie Stokholm +78
Since the onset of the `space revolution' of high-precision high-cadence photometry, asteroseismology has been demonstrated as a powerful tool for informing Galactic archaeology in…
The first view of Scuti and Doradus stars with the TESS mission
V. Antoci, M. S. Cunha, D. M. Bowman +63
We present the first asteroseismic results for Scuti and Doradus stars observed in Sectors 1 and 2 of the TESS mission. We utilise the 2-min cadence TESS data for a sample…
High-precision asteroseismology in Slowly Pulsating B star: HD 50230
Tao Wu, Yan Li
SPB star HD 50230, in fact a hybrid B-type pulsator, has been observed by CoRoT least 137 days. A nearly equidistant period spacing pattern are found among 8 modes which are extrac…
A new C-D-like diagram for SPB stars: The variations of period spacing as a signature of evolutionary status
Tao Wu, Yan Li, Zhen-min Deng
The Slowly Pulsating B-type (SPB) stars are the upper main-sequence stars on the HR diagram. Their oscillations are high-order, low-degree g-mode and can be used to probe the struc…
Which evolutionary status does the Blue Large-Amplitude Pulsators stay at?
Tao Wu, Yan Li
Asteroseismology is a very useful tool for exploring the stellar interiors and evolutionary status and for determining stellar fundamental parameters, such as stellar mass, radius,…
Frequency identification and asteroseismic analysis of the red giant KIC 9145955: fundamental parameters and helium core size
Xinyi Zhang, Tao Wu, Yan Li
We have analyzed 18 quarters of long-cadence data of KIC 9145955 provided by \emph{Kepler}, and extracted 61 oscillation frequencies from these high precision photometric data. The…
New Insights for High-precision Asteroseismology: Acoustic Radius of KIC 6225718
Tao Wu, Yan Li
Asteroseismology is a powerful tool for probing stellar interiors and determining stellar fundamental parameters. In previous works, -minimization method is usually used to fi…
Asteroseismic Study on Cluster Distance Moduli for RGB Stars in NGC 6791 and NGC 6819
Tao Wu, Yan Li, Saskia Hekker
Stellar distance is an important basic parameter in stellar astrophysics. Stars in a cluster are thought to be formed coevally from the same interstellar cloud of gas and dust. The…
