Probing the Origin of Stellar Flares on M dwarfs Using TESS Data Sectors 1-3
L. Doyle, G. Ramsay, J. G. Doyle +1
Detailed studies of the Sun have shown that sunspots and solar flares are closely correlated. Photometric data from Kepler/K2 has allowed similar studies to be carried out on other…
Kepler-62: A five-planet system with planets of 1.4 and 1.6 Earth radii in the Habitable Zone
W. J. Borucki, E. Agol, F. Fressin +62
We present the detection of five planets -- Kepler-62b, c, d, e, and f -- of size 1.31, 0.54, 1.95, 1.61 and 1.41 Earth radii, orbiting a K2V star at periods of 5.7, 12.4, 18.2, 12…
A possible misaligned orbit for the young planet AU Mic c
H. Yu, Z. Garai, M. Cretignier +98
The AU Microscopii planetary system is only 24 Myr old, and its geometry may provide clues about the early dynamical history of planetary systems. Here, we present the first measur…
The Hot Neptune WASP-166 b with ESPRESSO II: Confirmation of atmospheric sodium
J. V. Seidel, H. M. Cegla, L. Doyle +8
The hot Neptune desert, a distinct lack of highly irradiated planets in the size range of Neptune, remains one of the most intriguing results of exoplanet population studies. A dee…
Atmospheric characterisation and tighter constraints on the orbital misalignment of WASP-94 A b with HARPS
E. Ahrer, J. V. Seidel, L. Doyle +10
We present high spectral resolution observations of the hot Jupiter WASP-94 A b using the HARPS instrument on ESO's 3.6m telescope in La Silla, Chile. We probed for Na absorption i…
TESS observations of southern ultra fast rotating low mass stars
G. Ramsay, J. G. Doyle, L. Doyle
In our previous study of low mass stars using TESS, we found a handful which show a periodic modulation on a period <1 d but also displayed no flaring activity. Here we present the…
