Autor(es): Borges, Ernesto Pinheiro; Betzler, Alberto Silva
Abstract: Previous works have shown that some features of small bodies of the&#xD;
Solar System (mass, diameters, rotation periods, and apparent magnitudes) are relatively well modeled by distributions originally derived from Tsallis statistical mechanics.&#xD;
Some of the observed distributions are fitted in almost the entire range of the variables,&#xD;
different from other distributions. We revisit these previous studies and update them&#xD;
with recent data. Our results corroborate the previous ones, – that distributions based&#xD;
on the q-exponential family are usually found in statistical description of these planetary systems –, and reinforce the conjecture that the underlying mechanism that generates these observed data may have a nonextensive nature.

    <summary type="text">Título: O trabalho cientíﬁco de Sir William Herschel
Autor(es): Betzler, Alberto Silva
Abstract: Em 1781, Sir William Herschel foi o primeiro, em toda a história da Astronomia, a registrar a descoberta de um planeta. O planeta Urano, interpretado pelo próprio como um cometa, projetou-o ao patamar de uma celebridade conhecida em toda a Europa. Mais do que o descobridor de um planeta, Herschel foi um brilhante astrônomo e construtor de telescópios, tendo realizado observações sistemáticas que iniciaram novos campos de pesquisa astronômica. Tais pesquisas geraram importantes contribuições para&#xD;
entendimento do Sistema Solar e da galáxia que habitamos. Possuindo uma boa base em&#xD;
matemática e física percebe-se, nas pesquisas de Herschel, o uso constante do método científico e da física newtoniana.

Abstract: On June, 7th, 2019, around 01h33m (UT), inhabitantsfrom Brazil (mainly in the Southern Region states), Argentina,&#xD;
Paraguay and Uruguay observed a very bright fireball which was also recorded by two meteor monitoring stations&#xD;
of BRAMON. The fireball entered in the atmosphere with a velocity of 14.3 km/s at an altitude of 104 km over the&#xD;
south of Paraguay, travelling 393 km until reaching its dark flight at an altitude of 27.4 km over the state of Rio&#xD;
Grande do Sul. The calculated energy corresponds to an entry mass between 3.25 × 103 kg and 5.75 × 103 kg (this&#xD;
corresponds to a meteoroid with a diameter of 1.2 m to 1.4 m). It is believed that about 10% of the original mass&#xD;
reached the ground. The shallow trajectory created a large meteorite strewn field that could extend from the cities&#xD;
of Jari to Santa Maria (Rio Grande do Sul, Brazil). Teams conducted a meteorite search in the area, with no success&#xD;
so far.
