Observations of the 2023 February 27 fireball in northern Sweden using the auroral imaging system ALIS_4D
Gabriel Borderes-Motta, Daniel Kastinen, Tima Sergienko +7
On 2023 February 27 at 18:15:55.77 UT, a bright fireball streaked across the sky above northern Sweden. The event offered a valuable opportunity to study the phenomenon using an op…
The Moon as a possible source for Earth's co-orbital bodies
R. Sfair, L. C. Gomes, O. C. Winter +3
There is a growing number of Earth's co-orbital bodies being discovered. At least five of them are known to be temporarily in quasi-satellite orbits. One of those, 469219 Kamo'oale…
On the stability around Chariklo and the confinement of its rings
S. M. Giuliatti Winter, G. Madeira, T. Ribeiro +3
Chariklo has two narrow and dense rings, C1R and C2R, located at 391 km and 405 km, respectively. In the light of new stellar occultation data, we study the stability around Charik…
Dynamics around the binary system (65803) Didymos
R. Machado Oliveira, O. C. Winter, R. Sfair +3
Didymos and Dimorphos are primary and secondary, respectively, asteroids who compose a binary system that make up the set of Near Earth Asteroids (NEAs). They are targets of the Do…
(130) Elektra Delta -- on the stability of the new third moonlet
Giulia Valvano, Rai Machado Oliveira, Othon Cabo Winter +2
The aim of this work is to verify the stability of the proposed orbital solutions for the third moonlet (Delta) taking into account a realistic gravitational potential for the cent…
The Dynamics of Co-orbital Giant Exomoons -- Applications for the Kepler-1625 b and Kepler-1708 b Satellite Systems
Ricardo Moraes, Gabriel Borderes-Motta, Othon Cabo Winter +1
Exomoons are a missing piece of exoplanetary science. Recently, two promising candidates were proposed, Kepler-1625 b-I and Kepler-1708 b-I. While the latter still lacks a dynamica…
On the Stability of Additional Moons Orbiting Kepler-1625 b
Ricardo Moraes, Gabriel Borderes-Motta, Othon Cabo Winter +1
Since it was proposed the exomoon candidate Kepler-1625 b-I changed the way we see satellite systems. Because of its unusual physical characteristics, many questions about the stab…
Asteroid triple system 2001 SN263 : surfaces characteristics and dynamical environment
O. C. Winter, G. Valvano, T. S. Moura +3
The (153591) 2001 SN263 asteroid system, target of the first Brazilian interplanetary space mission, is one of the known three triple systems within the population of NEAs. One of…
Dynamical Environment and Surface Characteristics of Asteroid (16) Psyche
T. S. Moura, O. C. Winter, A. Amarante +3
Radar observations show that (16) Psyche is one of the largest and most massive asteroids of the M-class located in the main belt, with a diameter of approximately 230 km. This fac…
On the location of the ring around the dwarf planet Haumea
O. C. Winter1, G. Borderes-Motta1, T. Ribeiro
The recently discovered ring around the dwarf planet (136108) Haumea is located near the 1:3 resonance between the orbital motion of the ring particles and the spin of Haumea. In t…
APPROX -- Mutual approximations between the Galilean moons. The 2016-2018 observational campaign
B. Morgado, R. Vieira-Martins, M. Assafin +23
The technique of mutual approximations accurately gives the central instant at the maximum apparent approximation of two moving natural satellites in the sky plane. This can be use…
