The first confirmation of V-type asteroids among the Mars crosser population
چکیده انگلیسی


• We obtain reflectance spectra of selected asteroids in the Mars crossing region.
• We identify V-type asteroids among this population.
• We show that these asteroids may become Near Earth Asteroids.
• This supports an alternate link path between V-type Main Belt asteroids and NEAs.

The Mars crossing region constitutes a path to deliver asteroids from the Inner Main Belt to the Earth crossing space. While both the Inner Main Belt and the population of Earth crossing asteroids contains a significant fraction of asteroids belonging to the V taxonomic class, only two of such V-type asteroids has been detected in the Mars crossing region up to now. In this work, we systematically searched for asteroids belonging to the V class among the populations of Mars crossing asteroids, in order to support alternative paths to the delivery of these bodies into the Earth crossing region. We selected 18 candidate V-type asteroids in the Mars crossing region using observations contained in the Sloan Digital Sky Survey Moving Objects Catalog. Then, we observed 4 of these candidates to take their visible spectra using the Southern Astrophysical Research Telescope (SOAR). We also performed the numerical simulation of the orbital evolution of the observed asteroids. We confirmed that 3 of the observed asteroids belong to the V class, and one of these may follow a path that drives it to an Earth collision in some tens of million years.
