In an article published in the journal Icarus, researchers at São Paulo State University (UNESP) and collaborators report the findings of a study reconstituting the formation of the dwarf planet Ceres. The research was conducted by Rafael Ribeiro de Sousa, a professor in the program of graduate studies in physics on the Guaratinguetá campus. The co-authors of the article are Ernesto Vieira Neto, who was Ribeiro de Sousa's PhD thesis advisor, and researchers affiliated with [...]

On September 14, 2021, the GMTO Corporation welcomed the Weizmann Institute of Science into its international consortium of distinguished universities and research institutions building the Giant Magellan Telescope. The new partnership reinforces that completing the largest and most powerful Gregorian optical-infrared telescope ever engineered is a top priority for the global scientific community. The unprecedented abilities of the Giant Magellan Telescope coupled with the Weizmann Institute of [...]

A study conducted by scientists at São Paulo State University's Institute of Geosciences and Exact Sciences (IGCE-UNESP) in Rio Claro, Brazil, has identified 19 asteroids of interstellar origin classified as Centaurs, outer Solar System objects that revolve around the Sun in the region between the orbits of Jupiter and Neptune. An article on the study titled "An interstellar origin for high-inclination Centaurs" is published in the Royal Astronomical Society's Monthly [...]

Researchers at Sao Paulo State University identify groups of asteroids created by rotational fission inside collisional families. Billions of years ago, asteroid collisions resulted in the ejection of fragments hundreds of kilometers across and sharing similar orbits. The resulting groups are known as asteroid families. Other asteroid groups formed as a result of rotational fission, which happens when a rapidly spinning body reaches critical rotation speed and splits into relatively small [...]

Scientists have always thought about fission clusters as entirely distinct from collisional families. Now a study conducted by researchers affiliated with UNESP has shown that fission clusters may originate from collisional families in some cases Other asteroid groups formed as a result of rotational fission, which happens when a rapidly spinning body reaches critical rotation speed and splits into relatively small fragments only a few kilometers across. Scientists have always thought about [...]

Discovered in 2004, Haumea is a dwarf planet located beyond the orbit of Pluto in a region of the solar system called the Kuiper Belt. Pluto was demoted from the category of full-fledged planets in 2006 due to the discovery of Haumea and other dwarf planets. Haumea was officially recognized as a dwarf planet in 2008. Its ellipsoidal shape resembles that of the ball used in rugby or American football. It has two moons and a ring. Because of its ring, Haumea is a member of a group of objects in [...]

In the past three decades, almost 4,000 planet-like objects have been discovered orbiting isolated stars outside the Solar System (exoplanets). Beginning in 2011, it was possible to use NASA's Kepler Space Telescope to observe the first exoplanets in orbit around young binary systems of two live stars with hydrogen still burning in their core. Brazilian astronomers have now found the first evidence of the existence of an exoplanet orbiting an older or more evolved binary in which one of the [...]

Press Release From: FAPESP Posted: Tuesday, September 25, 2018 Press Release From: FAPESP   Four families of extremely young asteroids have been identified by researchers affiliated with São Paulo State University (UNESP) in Guaratinguetá, Brazil. An article on the discovery has been published in Monthly Notices of the Royal Astronomical Society. "We identified the new families by means of numerical simulation using the backward integration method (BIM), which is much more precise [...]

Released by Fundação de Amparo à Pesquisa do Estado de São Paulo A group of Brazilian researchers affiliated with the National Space Research Institute (INPE) is working to install a network comprised of magnetometers (instruments used to measure the intensity of a magnetic field) across South America. Known for its acronym Embrace MagNet (Embrace Magnetometer Network for South America), the project involves joint efforts from other Latin American institutions with the aim of studying [...]
