OGLE-2019-BLG-0825: Constraints on the Source System and Effect on Binary-lens Parameters arising from a Five Day Xallarap Effect in a Candidate Planetary Microlensing Event

Yuki K. Satoh, Naoki Koshimoto, David P. Bennett +86

We present an analysis of microlensing event OGLE-2019-BLG-0825. This event was identified as a planetary candidate by preliminary modeling. We find that significant residuals from…

Two transiting hot Jupiters from the WASP survey: WASP-150b and WASP-176b

Benjamin F. Cooke, Don Pollacco, Y. Almleaky +49

We report the discovery of two transiting exoplanets from the WASP survey, WASP-150b and WASP-176b. WASP-150b is an eccentric ( = 0.38) hot Jupiter on a 5.6 day orbit around a $…

OGLE-2013-BLG-0911Lb: A Secondary on the Brown-Dwarf Planet Boundary around an M-dwarf

Shota Miyazaki, Takahiro Sumi, David P. Bennett +92

We present the analysis of the binary-lens microlensing event OGLE-2013-BLG-0911. The best-fit solutions indicate the binary mass ratio of q~0.03 which differs from that reported i…

OGLE-2015-BLG-1649Lb: A gas giant planet around a low-mass dwarf

Masayuki Nagakane, Chien-Hsiu Lee, Naoki Koshimoto +66

We report the discovery of an exoplanet in microlensing event OGLE-2015-BLG-1649. The planet/host-star mass ratio is and the projected separation normalized…

Transit timing variations in the WASP-4 planetary system

John Southworth, M. Dominik, U. G. Jorgensen +25

Transits in the planetary system WASP-4 were recently found to occur 80s earlier than expected in observations from the TESS satellite. We present 22 new times of mid-transit that…

KELT-21b: A Hot Jupiter Transiting the Rapidly-Rotating Metal-Poor Late-A Primary of a Likely Hierarchical Triple System

Marshall C. Johnson, Joseph E. Rodriguez, George Zhou +65

We present the discovery of KELT-21b, a hot Jupiter transiting the A8V star HD 332124. The planet has an orbital period of days and a radius of $…

High-resolution Imaging of Transiting Extrasolar Planetary systems (HITEP). I. Lucky imaging observations of 101 systems in the southern hemisphere

D. F. Evans, J. Southworth, P. F. L. Maxted +33

(abridged) Context. Wide binaries are a potential pathway for the formation of hot Jupiters. The binary fraction among host stars is an important discriminator between competing fo…

New transit observations for HAT-P-30 b, HAT-P-37 b, TrES-5 b, WASP-28 b, WASP-36 b, and WASP-39 b

G. Maciejewski, D. Dimitrov, L. Mancini +14

We present new transit light curves for planets in six extrasolar planetary systems. They were acquired with 0.4-2.2 m telescopes located in west Asia, Europe, and South America. W…

Physical properties of the HAT-P-23 and WASP-48 planetary systems from multi-colour photometry

S. Ciceri, L. Mancini, J. Southworth +7

Accurate and repeated photometric follow-up observations of planetary-transit events are important to precisely characterize the physical properties of exoplanets. A good knowledge…

Physical properties of the WASP-67 planetary system from multi-colour photometry

L. Mancini, J. Southworth, S. Ciceri +29

The extrasolar planet WASP-67 b is the first hot Jupiter definitively known to undergo only partial eclipses. The lack of the second and third contact point in this planetary syste…

A lower radius and mass for the transiting extrasolar planet HAT-P-8b

L. Mancini, J. Southworth, S. Ciceri +10

Context. The extrasolar planet HAT-P-8 b was thought to be one of the more inflated transiting hot Jupiters. Aims. By using new and existing photometric data, we computed precise e…
