Extracting Asteroid Physical Properties from Vera C. Rubin Observatory Science Validation Survey Data: Rotational Periods, Colors, and Taxonomies
V. Carruba, S. Greenstreet, M. Mastropietro +7
The Vera C. Rubin Observatory will enable large-scale characterization of minor bodies through high-cadence, multi-band photometry. Early Science Validation (SV) observations from…
GravDyn: A Python Framework for Gravitational Modeling of Irregular Celestial Bodies Using Polyhedral, mascon, and Series Expansion Methods
Safwan Aljbaae, valerio Carruba, Allan K. de Almeida +4
GravDyn is an open-source Python package for computing gravitational potentials and accelerations around irregular celestial bodies. It implements three approaches within the same…
The dynamically hazardous asteroid 2025 TV. A new co-orbital asteroid of Venus
V. Carruba, R. Sfair, O. C. Winter
Twenty co-orbital asteroids of Venus are currently known, several of which may evolve into potentially hazardous asteroids (PHAs) over timescales of thousands of years. We report t…
A catalog of near-IR absolute magnitudes of Solar System small bodies
Alvaro Alvarez-Candal, Juan Luis Rizos, Milagros Colazo +5
Context. Phase curves of small bodies are useful tools to obtain their absolute magnitudes and phase coefficients. The former relates to the object's apparent brightness, while the…
The invisible threat: assessing the collisional hazard posed by the undiscovered Venus co-orbital asteroids
V. Carruba, R. Sfair, R. A. Araujo +7
Currently, 20 co-orbital asteroids of Venus are known, with only one with an eccentricity below 0.38. This is most likely caused by observational biases since asteroids with larger…
Main belt asteroids taxonomical information from Dark Energy Survey data
Valerio Carruba, Júlio I. B. Camargo, Safwan Aljbaae +2
While proper orbital elements are currently available for more than 1 million asteroids, taxonomical information is still lagging behind. Surveys like SDSS-MOC4 provided preliminar…
Optimization of Artificial Neural Networks models applied to the identification of images of asteroids' resonant arguments
Valerio Carruba, Safwan Aljbaae, Gabriel Caritá +2
The asteroidal main belt is crossed by a web of mean-motion and secular resonances, that occur when there is a commensurability between fundamental frequencies of the asteroids and…
Identifying the population of stable resonant asteroids using large databases
Valerio Carruba, Safwan Aljbaae, Rita de Cassia Domingos +2
Large observational surveys, like those that will be conducted at the Vera C. Rubin Observatory, are expected to discover up to one million new asteroids in the first year of opera…
Machine Learning applied to asteroid dynamics
V. Carruba, S. Aljbaae, R. C. Domingos +2
Machine Learning (ML) is the branch of computer science that studies computer algorithms that can learn from data. It is mainly divided into supervised learning, where the computer…
Probabilistic modeling of asteroid diameters from Gaia DR2 errors
Rafael S. de Souza, Alberto Krone-Martins, Valerio Carruba +5
The Gaia Data Release 2 provides precise astrometry for nearly 1.5 billion sources across the entire sky, including several thousand asteroids. In this work, we provide evidence th…
Influence of Apophis' spin axis variations on a spacecraft during the 2029 close approach with Earth
S. Aljbaae, J. Souchay, V. Carruba +2
Tumbling asteroids belong to a small group of objects, whose angular velocity vector is unaligned with any of its principal axes of inertia. This leads to challenging efforts to mo…
Artificial Neural Network classification of asteroids in the M1:2 mean-motion resonance with Mars
V. Carruba, S. Aljbaae, R. C. Domingos +1
Artificial neural networks (ANN) have been successfully used in the last years to identify patterns in astronomical images. The use of ANN in the field of asteroid dynamics has bee…
Analysis of the Karma asteroid family
Debora Pavela, Bojan Novaković, Valerio Carruba +1
The Karma asteroid family is a group of primitive asteroids in the middle part of the main belt, just at the outer edge of the 3J:1A mean-motion resonance. We obtained the list of…
Asteroid families interacting with secular resonances
V. Carruba, D. Vokrouhlický, B. Novakovic
Asteroid families are formed as the result of collisions. Large fragments are ejected with speeds of the order of the escape velocity from the parent body. After the family formati…
On the age of the Nele asteroid family
V. Carruba, D. Vokrouhlický, D. +2
The Nele group, formerly known as the Iannini family, is one of the youngest asteroid families in the main belt. Previously, it has been noted that the pericenter longitudes $\varp…
An automatic approach to exclude interlopers from asteroid families
V. Radović, B. Novaković, V. Carruba +1
Asteroid families are valuable source of information to many asteroid-related re- searches, assuming a reliable list of their members could be obtained. However, as the number of k…
Detection of the Yarkovsky effect for C-type asteroids in the Veritas family
Valerio Carruba, David Vokrouhlický, David Nesvorný
The age of a young asteroid family can be determined by tracking the orbits of family members backward in time and showing that they converge at some time in the past. Here we cons…
Scattering V-type asteroids during the giant planets instability: A step for Jupiter, a leap for basalt
Pedro Brasil, Fernando Roig, David Nesvorný +1
V-type asteroids are a taxonomic class whose surface is associated to a basaltic composition. The only known source of V-type asteroids in the Main Asteroid Belt is (4) Vesta, that…
The Hoffmeister asteroid family
V. Carruba, B. Novakovic, S. Aljbaae
The Hoffmeister family is a C-type group located in the central main belt. Dynamically, it is important because of its interaction with the nodal secular resonance with Ce…
