Spin-orbit alignments for Three Transiting Hot Jupiters: WASP-103b, WASP-87b, & WASP-66b
B. C. Addison, C. G. Tinney, D. J. Wright +1
We have measured the sky-projected spin-orbit alignments for three transiting Hot Jupiters, WASP-103b, WASP-87b, and WASP-66b, using spectroscopic measurements of the Rossiter-McLa…
A Spin-Orbit Alignment for the Hot Jupiter HATS-3b
B. C. Addison, C. G. Tinney, D. J. Wright +1
We have measured the alignment between the orbit of HATS-3b (a recently discovered, slightly inflated Hot Jupiter) and the spin-axis of its host star. Data were obtained using the…
HATS-1b: The First Transiting Planet Discovered by the HATSouth Survey
K. Penev, G. Ã. Bakos, D. Bayliss +25
We report the discovery of HATS-1b, a transiting extrasolar planet orbiting the moderately bright V=12.05 G dwarf star GSC 6652-00186, and the first planet discovered by HATSouth,…
HATS-13b and HATS-14b: two transiting hot Jupiters from the HATSouth survey
L. Mancini, J. D. Hartman, K. Penev +23
We report the discovery of HATS-13b and HATS-14b, two hot-Jupiter transiting planets discovered by the HATSouth survey. The host stars are quite similar to each other (HATS-13: V =…
HATS-2b: A transiting extrasolar planet orbiting a K-type star showing starspot activity
M. Mohler-Fischer, L. Mancini, J. D. Hartman +24
We report the discovery of HATS-2b, the second transiting extrasolar planet detected by the HATSouth survey. HATS-2b is moving on a circular orbit around a V=13.6 mag, K-type dwarf…
A Nearly Polar Orbit for the Extrasolar Hot Jupiter WASP-79b
B. C. Addison, C. G. Tinney, D. J. Wright +5
We report the measurement of a spin-orbit misalignment for WASP-79b, a recently discovered, bloated transiting hot Jupiter from the WASP survey. Data were obtained using the CYCLOP…
The Spin-orbit alignment of two short period eclipsing binary systems
Tony Wells, B. C. Addison, R. A. Wittenmyer +8
We present a joint analysis of TESS photometry and radial velocity measurements obtained from the Minerva-Australis facility for two short-period eclipsing binaries, TIC 48227288 a…
Stellar Obliquities & Planetary Alignments (SOPA) I. Spin-Orbit measurements of Three Transiting Hot Jupiters: WASP-72b, WASP-100b, & WASP-109b
B. C. Addison, S. Wang, M. C. Johnson +3
We report measurements of the sky-projected spin--orbit angles for three transiting hot Jupiters: two of which are in nearly polar orbits, WASP-100b and WASP-109b, and a third in a…
The obliquity and atmosphere of the ultra-hot Jupiter TOI-1431b (MASCARA-5b): A misaligned orbit and no signs of atomic ormolecular absorptions
M. Stangret, E. Pallé, N. Casasayas-Barris +21
Ultra-hot Jupiters are defined as giant planets with equilibrium temperatures larger than 2000 K. Most of them are found orbiting bright A-F type stars, making them extremely suita…
Planets around young active Solar-type stars: Assessing detection capabilities from a non stabilised spectrograph
A. Heitzmann, S. C. Marsden, P. Petit +8
Short-orbit gas giant planet formation/evolution mechanisms are still not well understood. One promising pathway to discriminate between mechanisms is to constrain the occurrence r…
