HATPI Pre-Perihelion Time-series Photometry of the Interstellar Comet 3I/ATLAS

Joel D. Hartman, Gáspár Á. Bakos, Andrés Jordán +10

HATPI is a recently commissioned time-domain facility at Las Campanas Observatory, Chile, that uses 64 wide-angle, 9.6 cm diameter lenses and back-illuminated CCDs, yielding a mosa…

A Compact Multi-Planet System of Three Transiting Giant Planets Around TIC118798035

Rafael Brahm, Trifon Trifonov, Andrés Jordán +20

We report the discovery and characterization of three transiting giant planets in the TIC118798035 system. The three planets were identified as transiting candidates from data of t…

MANGOS II: Five new giant planets orbiting low-mass stars

G. Dransfield, M. Timmermans, D. Sebastian +47

Giant planets orbiting low-mass stars on short orbits present a conundrum, as in the most extreme cases their existence cannot be reconciled with current models of core accretion.…

A transiting giant planet in orbit around a 0.2-solar-mass host star

Edward M. Bryant, Andrés Jordán, Joel D. Hartman +56

Planet formation models suggest that the formation of giant planets is significantly harder around low-mass stars, due to the scaling of protoplanetary disc masses with stellar mas…
