A decade of transit photometry for K2-19: Revised system architecture
J. M. Almenara, R. Mardling, A. Leleu +21
The star K2-19 hosts a pair of Neptunian planets deep inside the 3:2 resonance. They induce strong transit-timing variations with two incommensurate frequencies. Previous photodyna…

The water molecule is a key ingredient in the formation of planetary systems, with the water snowline being a favourable location for the growth of massive planetary cores. Here we…
Short-lived radioisotope enrichment in star-forming regions from stellar winds and supernovae
Richard J. Parker, Tim Lichtenberg, Miti Patel +2
The abundance of the short-lived radioisotopes 26-Al and 60-Fe in the early Solar system is usually explained by the Sun either forming from pre-enriched material, or the Sun's pro…

We present and analyze 58 transit light curves of TrES-3b and 98 transit light curves of Qatar-1b observed by Transiting Exoplanet Survey Satellite (TESS), plus two transit light c…
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…

Aims. We aim to increase the contrast limits to detect new satellites orbiting known asteroids. We use cutting-edge data reduction techniques and data processing algorithms that ar…
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…
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…
Monitoring polarization in comet 46P/Wirtanen
M. Zheltobryukhov, E. Zubko, E. Chornaya +9
We measure the degree of linear polarization of comet 46P/Wirtanen during two months, embracing the perihelion passage in 2018 December with phase angles ranging from α=18.1 to 46.…
Are There Transit Timing Variations for the Exoplanet Qatar-1b ?
Li-Hsin Su, Ing-Guey Jiang, Devesh P. Sariya +11
Motivated by the unsettled conclusion on whether there are any transit timing variations (TTVs) for the exoplanet Qatar-1b, 10 new transit light curves are presented and the TTV an…
