Pre-perihelion detection of a wobbling high-latitude jet in the interstellar comet 3I/ATLAS
M. Serra-Ricart, J. Licandro, M. R. Alarcon
We present observations of the detection of a faint high-latitude jet in the inner coma of comet 3I/ATLAS that coincides with the broad plume detected in visible images along PA $2…
Assessing interstellar comet 3I/ATLAS with the 10.4 m Gran Telescopio Canarias and the Two-meter Twin Telescope
R. de la Fuente Marcos, M. R. Alarcon, J. Licandro +8
Context. Theories of the formation and evolution of small bodies in planetary systems predict that they may escape into interstellar space at any time. After having characterized j…
Shape and spin-state model of tumbling asteroid (319) Leona
J. Äurech, J. L. Ortiz, M. Ferrais +14
Stellar occultations by asteroids observed from several stations are routinely used to reconstruct the asteroid's sky-plane projections. Together with the asteroid's shape model re…
Basaltic quasi-mini-moon: Characterizing 2024 PT5 with the 10.4 m Gran Telescopio Canarias and the Two-meter Twin Telescope
R. de la Fuente Marcos, J. de Leon, M. Serra-Ricart +8
Context. Small bodies in Earth-like orbits, the Arjunas, are good targets for scientific exploration, and space mining or in situ resource utilization (ISRU) trials as they enable…
