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…
Discovery of a hot, transiting, Earth-sized planet and a second temperate, non-transiting planet around the M4 dwarf GJ 3473 (TOI-488)
J. Kemmer, S. Stock, D. Kossakowski +93
We present the confirmation and characterisation of GJ 3473 b (G 50--16, TOI-488.01), a hot Earth-sized planet orbiting an M4 dwarf star, whose transiting signal ($P=1.1980035\pm0.…
Cluster Difference Imaging Photometric Survey. II. TOI 837: A Young Validated Planet in IC 2602
L. G. Bouma, J. D. Hartman, R. Brahm +42
We report the discovery of TOI 837b and its validation as a transiting planet. We characterize the system using data from the NASA TESS mission, the ESA Gaia mission, ground-based…
Obliquity measurement and atmospheric characterization of the WASP-74 planetary system
R. Luque, N. Casasayas-Barris, H. Parviainen +27
We present new transit observations of the hot Jupiter WASP-74 b ( 1860 K) using the high-resolution spectrograph HARPS-N and the multi-colour simultaneous imag…
First Detection of Two Superoutbursts during Rebrightening Phase of a WZ Sge-type Dwarf Nova: TCP J21040470+4631129
Yusuke Tampo, Kojiguchi Naoto, Keisuke Isogai +51
We report photometric and spectroscopic observations and analysis of the 2019 superoutburst of TCP J21040470+4631129. This object showed a 9-mag superoutburst with early superhumps…
