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…
Planetary candidates transiting cool dwarf stars from Campaigns 12 to 15 of K2
A. Castro González, E. Díez Alonso, J. Menéndez Blanco +15
We analyzed the photometry of 20038 cool stars from campaigns 12, 13, 14 and 15 of the K2 mission in order to detect, characterize and validate new planetary candidates transiting…
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…
