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…
Asteroseismology of the Multiplanet System K2-93
Mikkel N. Lund, Emil Knudstrup, Victor Silva Aguirre +14
We revisit the analysis of the bright multiplanet system K2-93, discovered with data taken by the K2 mission. This system contains five identified planets ranging in size from sub-…
TESS Asteroseismology of the known red-giant host stars HD 212771 and HD 203949
Tiago L. Campante, Enrico Corsaro, Mikkel N. Lund +45
The Transiting Exoplanet Survey Satellite (TESS) is performing a near all-sky survey for planets that transit bright stars. In addition, its excellent photometric precision enables…
TOI-503: The first known brown dwarf-Am star binary from the TESS mission
Ján Šubjak, Rishikesh Sharma, Theron W. Carmichael +76
We report the discovery of an intermediate-mass transiting brown dwarf, TOI-503b, from the TESS mission. TOI-503b is the first brown dwarf discovered by TESS and orbits a metallic-…
The subgiant HR 7322 as an asteroseismic benchmark star
Amalie Stokholm, Poul Erik Nissen, Victor Silva Aguirre +5
We present an in-depth analysis of the bright subgiant HR 7322 (KIC 10005473) using Kepler short-cadence photometry, optical interferometry from CHARA, high-resolution spectra from…
Signatures of magnetic activity: On the relation between stellar properties and p-mode frequency variations
A. R. G. Santos, T. L. Campante, W. J. Chaplin +12
In the Sun, the properties of acoustic modes are sensitive to changes in the magnetic activity. In particular, mode frequencies are observed to increase with increasing activity le…
