Nodal Precession of WASP-33b for Eleven Years by Doppler Tomographic and Transit Photometric Observations

Noriharu Watanabe, Norio Narita, Enric Palle +14

WASP-33b, a hot Jupiter around a hot star, is a rare system in which nodal precession has been discovered. We updated the model for the nodal precession of WASP-33b by adding new o…

Is the orbit of the exoplanet WASP-43b really decaying? TESS and MuSCAT2 observations confirm no detection

Z. Garai, T. Pribulla, H. Parviainen +24

Up to now, WASP-12b is the only hot Jupiter confirmed to have a decaying orbit. The case of WASP-43b is still under debate. Recent studies preferred or ruled out the orbital decay…

TOI-1749: an M dwarf with a Trio of Planets including a Near-Resonant Pair

A. Fukui, J. Korth, J. H. Livingston +65

We report the discovery of one super-Earth- (TOI-1749b) and two sub-Neptune-sized planets (TOI-1749c and TOI-1749d) transiting an early M dwarf at a distance of 100~pc, which were…

Two Bright M Dwarfs Hosting Ultra-Short-Period Super-Earths with Earth-like Compositions

Teruyuki Hirano, John H. Livingston, Akihiko Fukui +58

We present observations of two bright M dwarfs (TOI-1634 and TOI-1685: ) hosting ultra-short period (USP) planets, identified by the TESS mission. The two stars are simi…

TOI-519 b: a short-period substellar object around an M dwarf validated using multicolour photometry and phase curve analysis

H. Parviainen, E. Palle, M. R. Zapatero-Osorio +43

Context: We report the discovery of TOI-519 b (TIC 218795833), a transiting substellar object (R = 1.07 RJup) orbiting a faint M dwarf (V = 17.35) on a 1.26 d orbit. Brown dwarfs a…

An enhanced slope in the transmission spectrum of the hot Jupiter WASP-104b

G. Chen, E. Palle, H. Parviainen +25

We present the optical transmission spectrum of the hot Jupiter WASP-104b based on one transit observed by the blue and red channels of the DBSP spectrograph at the Palomar 200-inc…
