TESS Giants Transiting Giants V -- Two hot Jupiters orbiting red-giant hosts
Filipe Pereira, Samuel K. Grunblatt, Angelica Psaridi +24
In this work we present the discovery and confirmation of two hot Jupiters orbiting red-giant stars, TOI-4377 b and TOI-4551 b, observed by TESS in the southern ecliptic hemisphere…
Evidence of structural discontinuities in the inner core of red-giant stars
Mathieu Vrard, Margarida S. Cunha, Diego Bossini +3
Red giants are stars in the late stages of stellar evolution. Because they have exhausted the supply of hydrogen in their core, they burn the hydrogen in the surrounding shell. Onc…
Signatures of magnetic activity in the seismic data of solar-type stars observed by Kepler
A. R. G. Santos, T. L. Campante, W. J. Chaplin +8
In the Sun, the frequencies of the acoustic modes are observed to vary in phase with the magnetic activity level. These frequency variations are expected to be common in solar-type…
The influence of metallicity on stellar differential rotation and magnetic activity
Christoffer Karoff, Travis S. Metcalfe, Angela R. G. Santos +20
Observations of Sun-like stars over the last half-century have improved our understanding of how magnetic dynamos, like that responsible for the 11-year solar cycle, change with ro…
Measurement of acoustic glitches in solar-type stars from oscillation frequencies observed by Kepler
A. Mazumdar, M. J. P. F. G. Monteiro, J. Ballot +15
For the very best and brightest asteroseismic solar-type targets observed by Kepler, the frequency precision is sufficient to determine the acoustic depths of the surface convectiv…
Variable Stars
G. Handler, K. R. Pollard, M. S. Cunha +10
This is the triennial report of IAU Commission 27, mostly presenting a review of recent advances in the field.
