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…
Revisiting the Red-giant Branch Hosts KOI-3886 and Draconis. Detailed Asteroseismic Modeling and Consolidated Stellar Parameters
Tiago L. Campante, Tanda Li, J. M. Joel Ong +23
Asteroseismology is playing an increasingly important role in the characterization of red-giant host stars and their planetary systems. Here, we conduct detailed asteroseismic mode…
Glitches in solar-like oscillating F-type stars: Theoretical signature of the base of the convective envelope on the ratios
M. Deal, M. -J. Goupil, M. S. Cunha +7
The transition between convective and radiative stellar regions is still not fully understood. The sharp variations in sound speed located in these transition regions give rise to…
FRA -- A new Fast, Robust and Automated pipeline for the detection and measurement of solar-like oscillations in time-series photometry of red-giant stars
C. Gehan, T. L. Campante, M. S. Cunha +1
We developed, tested and validated a new Fast, Robust and Automated (FRA) tool to detect solar-like oscillations. FRA is based on the detection and measurement of the frequency of…
Detection and characterization of planets orbiting oscillating red-giant stars with NASA's TESS mission
Filipe Pereira
Driven largely by multiple ground-based radial-velocity (RV) surveys and photometric space missions such as Kepler and K2, the discovery of new exoplanets has increased rapidly sin…
TESS Giants Transiting Giants II: The hottest Jupiters orbiting evolved stars
Samuel K. Grunblatt, Nicholas Saunders, Meng Sun +42
Giant planets on short-period orbits are predicted to be inflated and eventually engulfed by their host stars. However, the detailed timescales and stages of these processes are no…
TESS Data for Asteroseismology: Light Curve Systematics Correction
Mikkel N. Lund, Rasmus Handberg, Derek L. Buzasi +7
Data from the Transiting Exoplanet Survey Satellite (TESS) has produced of order one million light curves at cadences of 120 s and especially 1800 s for every ~27-day observing sec…
Uncovering the ultimate planet impostor. An eclipsing brown dwarf in a hierarchical triple with two evolved stars
J. Lillo-Box, Á. Ribas, B. Montesinos +14
Exoplanet searches through space-based photometric time series have shown to be very efficient in recent years. However, follow-up efforts on the detected planet candidates have be…
Improving transit characterisation with Gaussian process modelling of stellar variability
S. C. C. Barros, O. Demangeon, R. F. Díaz +4
New photometric space missions to detect and characterise transiting exoplanets are focusing on bright stars to obtain high cadence, high signal-to-noise light curves. Since these…
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…
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…
Gaussian Process modelling of granulation and oscillations in red-giant stars
Filipe Pereira, Tiago L. Campante, Margarida S. Cunha +6
The analysis of photometric time series in the context of transiting planet surveys suffers from the presence of stellar signals, often dubbed "stellar noise". These signals, cause…
A Hot Saturn Orbiting An Oscillating Late Subgiant Discovered by TESS
Daniel Huber, William J. Chaplin, Ashley Chontos +139
We present the discovery of TOI-197.01, the first transiting planet identified by the Transiting Exoplanet Survey Satellite (TESS) for which asteroseismology of the host star is po…
Synergy between asteroseismology and exoplanet science: an outlook
Tiago L. Campante, Susana C. C. Barros, Olivier Demangeon +5
Space-based asteroseismology has been playing an important role in the characterization of exoplanet-host stars and their planetary systems. The future looks even brighter, with sp…
