Hoy, cuando toda la Humanidad espera una vacuna o un tratamiento eficaz para el coronavirus COVID-19, tenemos que recordar que en muchos descubrimientos...
Size and albedo distributions of asteroids in cometary orbits using WISE data
Context. Determining whether asteroids in cometary orbits (ACOs) are dormant or extinct comets is relevant for understanding the end-states of comets and the...
Small bodies and big impacts: comets, asteroids, and the origin of water and organics on Earth
The role of asteroids and comet impacts on the origin of Earth’s water and organic molecules is reviewed. Earth is believed to have formed dry, and magma oceans...
Solar oscillations and the effect of a comet impact
If such external influences as the impact of a comet on the solar surface could destroy or mask the coherence of observed solar oscillations, the scope and...
Spectral properties of asteroids in cometary orbits
Aims: In this paper we analyze the spectra of a sample of asteroids in cometary orbits (ACOs) in order to understand the relationship between them, the Jupiter...
Spectroscopic and dynamical properties of comet C/2018 F4, likely a true average former member of the Oort cloud
Context. The population of comets hosted by the Oort cloud is heterogeneous. Most studies in this area have focused on highly active objects, those with small...
Spectroscopic observations of new Oort cloud comet 2006 VZ13 and four other comets
Spectral data are presented for comets 2006 VZ13 (LINEAR), 2006 K4 (NEAT), 2006 OF2 (Broughton), 2P/Encke and 93P/Lovas I, obtained with the Cerro Tololo Inter...
Spitzer observations of the asteroid-comet transition object and potential spacecraft target 107P (4015) Wilson-Harrington
Context: Near-Earth asteroid-comet transition object 107P/ (4015) Wilson-Harrington is a possible target of the joint European Space Agency (ESA) and Japanese...
