OGLE-2015-BLG-1395Lb: A Cold Sub-Saturn Mass Planet Orbiting an M Dwarf
Andrew A. Cole, Joshua W. Blackman, Jean-Philippe Beaulieu +75
We present an analysis of the high-magnification microlensing event OGLE-2015-BLG-1395 and report the discovery of a sub-Saturn mass companion to the lens. Photometric coverage of…
The Neptunian ridge planet WASP-156 b does not have a polar orbit
M. Lafarga, J. I. Espinoza-Retamal, H. M. Cegla +26
The population of short-period exo-Neptunes is thought to be shaped by an interplay between different dynamical mechanisms, such as orbital migration and tidal effects, and photoev…
Long-term monitoring of WASP-19 b: Signs of apsidal precession and molecular signatures
A. R. Rajkumar, A. Bayo, P. Peng +30
With more than 6000 exoplanets discovered so far, about 12 percent are hot Jupiters. Their large sizes and short orbital periods make them valuable targets for studying planetary f…
Time-Domain Photometry and Activity Evolution of Interstellar Comet 3I/ATLAS with BHTOM
A. Fraser Gillan, Łukasz Wyrzykowski, Przemysław J. Mikołajczyk +69
Time-domain photometric monitoring is essential for characterizing cometary evolution, particularly for rare interstellar objects with limited observing opportunities. We aimed to…
TEPCat: The Transiting Extrasolar Planet Catalogue
John Southworth
Transiting extrasolar planets are extraordinarily valuable for understanding the characteristics and formation of planets, because they are the only exoplanets whose physical and o…
Chasing the Tides: Searching for Orbital Decay Signatures in Transit Timing Data and Tidal Models for 20 Hot Jupiters
A. C. Kutluay, Ö. Baştürk, Adrian J. Barker +31
In this work, we present a transit timing variation analysis for 20 hot Jupiter systems, which we interpret with theoretical tidal dissipation models. For the majority of the sampl…
Doomed Worlds II: Reassessing Suggestions of Orbital Decay for TrES-5 b
Marvin Rothmeier, Elisabeth R. Adams, Karsten Schindler +9
TrES-5b is one of only three ultra-hot Jupiters (UHJs) with suggestions of a possibly decreasing orbital period that have persisted through multiple independent analyses (G. Maciej…
Using Stellar Spectral Energy Distributions to Measure Exoplanet Parameters
Sam Morrell, Tim Naylor, John Southworth +1
The ability to make accurate determinations of planetary parameters is inextricably linked to measuring physical parameters of the host star, in particular the stellar radius. In t…
EBOP MAVEN: A machine learning model to estimate the input parameters for analytic fitting of detached eclipsing binary light curves
Stephen Overall, John Southworth
Detached eclipsing binary stars (dEBs) are a key source of data on fundamental stellar parameters. Within the light curve databases of survey missions such as Kepler and TESS are a…
Evidence for conservative mass transfer in the classical Algol system Librae from its surface carbon-to-nitrogen abundance ratio
A. Dervisoglu, K. Pavlovski, H. Lehmann +2
Algol-type binary systems are the product of rapid mass transfer between the initially more massive component to its companion. It is still unknown whether the process is conservat…
Deciphering the atmosphere of HAT-P-12b: solving discrepant results
X. Alexoudi, M. Mallonn, C. von Essen +9
Two independent investigations of the atmosphere of the hot Jupiter HAT-P-12b by two different groups resulted in discrepant solutions. Using broad-band photometry from the ground,…
Oscillating red giants in eclipsing binary systems: empirical reference value for asteroseismic scaling relation
N. Themeßl, S. Hekker, J. Southworth +10
The internal structures and properties of oscillating red-giant stars can be accurately inferred through their global oscillation modes (asteroseismology). Based on 1460 days of Ke…
WASP-157b, a Transiting Hot Jupiter Observed with K2
T. Močnik, D. R. Anderson, D. J. A. Brown +17
We announce the discovery of the transiting hot Jupiter WASP-157b in a 3.95-d orbit around a V = 12.9 G2 main-sequence star. This moderately inflated planet has a Saturn-like densi…
Pathway to the Galactic Distribution of Planets: Combined Spitzer and Ground-Based Microlens Parallax Measurements of 21 Single-Lens Events
S. Calchi Novati, A. Gould, A. Udalski +82
We present microlens parallax measurements for 21 (apparently) isolated lenses observed toward the Galactic bulge that were imaged simultaneously from Earth and Spitzer, which was…
Three WASP-South transiting exoplanets: WASP-74b, WASP-83b & WASP-89b
Coel Hellier, D. R. Anderson, A. Collier Cameron +16
We report the discovery of three new transiting hot Jupiters by WASP-South together with the TRAPPIST photometer and the Euler/CORALIE spectrograph. WASP-74b orbits a star of V = 9…
OGLE-2011-BLG-0265Lb: a Jovian Microlensing Planet Orbiting an M Dwarf
J. Skowron, I. -G. Shin, A. Udalski +121
We report the discovery of a Jupiter-mass planet orbiting an M-dwarf star that gave rise to the microlensing event OGLE-2011-BLG-0265. Such a system is very rare among known planet…
