Investigation of Transit Timing and an Optical Transmission Spectrum of the Hot Jupiter WASP-11 b
Napaporn A-thano, Supachai Awiphan, Eamonn Kerins +15
WASP-11~b/HAT-P-10~b is an inflated hot Jupiter, which has a low density that makes it a good target for atmospheric studies using the transmission spectroscopy technique. In this…
Transit Timing Variation of K2-237b: Hints Toward Planet Disk Migration
Fan Yang, Richard J. Long, Eamonn Kerins +8
Hot Jupiters should initially form at considerable distances from host stars and subsequently migrate towards inner regions, supported directly by transit timing variation (TTV). W…
A close binary lens revealed by the microlensing event Gaia20bof
E. Bachelet, P. Rota, V. Bozza +24
During the last 25 years, hundreds of binary stars and planets have been discovered towards the Galactic Bulge by microlensing surveys. Thanks to a new generation of large-sky surv…
Revisiting the Transit Timing and Atmosphere Characterization of the Neptune-mass Planet HAT-P-26 b
Napaporn A-thano, Supachai Awiphan, Ing-Guey Jiang +11
We present the transit timing variation (TTV) and planetary atmosphere analysis of the Neptune-mass planet HAT-P-26~b. We present a new set of 13 transit light curves from optical…
Earth through the looking glass: how frequently are we detected by other civilisations through photometric microlensing?
S. Suphapolthaworn, S. Awiphan, T. Chatchadanoraset +5
Microlensing is proving to be one of the best techniques to detect distant, low-mass planets around the most common stars in the Galaxy. In principle, Earth's microlensing signal c…
Euclid-Roman joint microlensing survey: early mass measurement, free floating planets and exomoons
Etienne Bachelet, David Specht, Matthew Penny +12
As the Kepler mission has done for hot exoplanets, the ESA Euclid and NASA Roman missions have the potential to create a breakthrough in our understanding of the demographics of co…
The Transit Timing and Atmosphere of Hot Jupiter HAT-P-37b
Napaporn A-thano, Ing-Guey Jiang, Supachai Awiphan +13
The transit timing variation (TTV) and transmission spectroscopy analyses of the planet HAT-P-37b, which is a hot Jupiter orbiting an G-type star, were performed. Nine new transit…
Eclipse timing variations in the WD+dM eclipsing binary RR Cae
R. Rattanamala, S. Awiphan, S. Komonjinda +9
We present the binary model and the eclipse timing variations of the eclipsing binary RR Cae, which consists of a white dwarf eclipsed by an M-type dwarf companion. The multi-wavel…
A transit timing variation observed for the long-period extremely low density exoplanet HIP 41378f
Edward M. Bryant, Daniel Bayliss, Alexandre Santerne +47
HIP 41378 f is a temperate planet with period of 542.08 days and an extremely low density of g cm. It transits the bright star HIP 41378…
TransitFit: combined multi-instrument exoplanet transit fitting for JWST, HST and ground-based transmission spectroscopy studies
J. J. C. Hayes, A. Priyadarshi, E. Kerins +19
We present TransitFit, a package designed to fit exoplanetary transit light-curves. TransitFit offers multi-epoch, multi-wavelength fitting of multi-telescope transit data. Transit…

An Unusual Transmission Spectrum for the Sub-Saturn KELT-11b Suggestive of a Sub-Solar Water Abundance
Knicole D. Colón, Laura Kreidberg, Luis Welbanks +30
We present an optical-to-infrared transmission spectrum of the inflated sub-Saturn KELT-11b measured with the Transiting Exoplanet Survey Satellite (TESS), the Hubble Space Telesco…
Optimizing exoplanet atmosphere retrieval using unsupervised machine-learning classification
Joshua J. C. Hayes, E. Kerins, S. Awiphan +6
One of the principal bottlenecks to atmosphere characterisation in the era of all-sky surveys is the availability of fast, autonomous and robust atmospheric retrieval methods. We p…
