TOI-2266 b: a keystone super-Earth at the edge of the M dwarf radius valley

Hannu Parviainen, Felipe Murgas, Emma Esparza-Borges +59

We validate the Transiting Exoplanet Survey Satellite (TESS) object of interest TOI-2266.01 (TIC 348911) as a small transiting planet (most likely a super-Earth) orbiting a faint M…

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…

MuSCAT2 multicolour validation of TESS candidates: an ultra-short-period substellar object around an M dwarf

H. Parviainen, E. Palle, M. R. Zapatero-Osorio +37

We report the discovery of TOI 263.01 (TIC 120916706), a transiting substellar object (R = 0.87 RJup) orbiting a faint M3.5~V dwarf (V=18.97) on a 0.56~d orbit. We set out to deter…

Dust Properties of Double-Tailed Active Asteroid (6478) Gault

F. Moreno, E. Jehin, J. Licandro +11

Asteroid (6478) Gault was discovered to exhibit a comet-like tail in observations from December 2018, becoming a new member of the so-called active asteroid population in the main…

280 one-opposition near-Earth asteroids recovered by the EURONEAR with the Isaac Newton Telescope

O. Vaduvescu, L. Hudin, T. Mocnik +80

One-opposition near-Earth asteroids (NEAs) are growing in number, and they must be recovered to prevent loss and mismatch risk, and to improve their orbits, as they are likely to b…
