Exoplanet Aeronomy: A Case Study of WASP-69b's Variable Thermosphere
W. Garrett Levine, Shreyas Vissapragada, Adina D. Feinstein +5
Aeronomy, the study of Earth's upper atmosphere and its interaction with the local space environment, has long traced changes in the thermospheres of Earth and other solar system p…
TOI-519 b: a short-period substellar object around an M dwarf validated using multicolour photometry and phase curve analysis
H. Parviainen, E. Palle, M. R. Zapatero-Osorio +43
Context: We report the discovery of TOI-519 b (TIC 218795833), a transiting substellar object (R = 1.07 RJup) orbiting a faint M dwarf (V = 17.35) on a 1.26 d orbit. Brown dwarfs a…
On the sensitivity of gravito-inertial modes to differential rotation in intermediate-mass main-sequence stars
T. Van Reeth, J. S. G. Mombarg, S. Mathis +9
Context. While rotation has a major impact on stellar structure and evolution, its effects are not well understood. Thanks to high- quality and long timebase photometric observatio…
Evidence of chaotic modes in the analysis of four delta Scuti stars
S. Barceló Forteza, T. Roca Cortés, A. García Hernandez +1
Since CoRoT observations unveiled the very low amplitude modes that form a flat plateau in the power spectrum structure of delta Scuti stars, the nature of this phenomenon, includi…
Pulsation spectrum of Delta Sct stars: the binary HD 50870 as seen with CoRoT and HARPS
L. Mantegazza, E. Poretti, E. Michel +14
We present the results obtained with the CoRoT satellite for HD 50870, a Delta Sct star which was observed for 114.4 d. The 307,570 CoRoT datapoints were analysed with different te…
Age determination of the HR8799 planetary system using asteroseismology
A. Moya, P. J. Amado, D. Barrado +4
Discovery of the first planetary system by direct imaging around HR8799 has made the age determination of the host star a very important task. This determination is the key to deri…
The asteroseismic potential of Kepler: first results for solar-type stars
W. J. Chaplin, T. Appourchaux, Y. Elsworth +105
We present preliminary asteroseismic results from Kepler on three G-type stars. The observations, made at one-minute cadence during the first 33.5d of science operations, reveal hi…
Hybrid gamma Doradus - delta Scuti pulsators: New insights into the physics of the oscillations from Kepler observations
A. Grigahcene, V. Antoci, L. Balona +39
Observations of the pulsations of stars can be used to infer their interior structure and test theoretical models. The main sequence Doradus (Dor) and Scuti (Sct) stars wit…
