The collisional evolution of undifferentiated asteroids and the formation of chondritic meteoroids
(IOP Publishing, 2016-06)
Most meteorites are fragments from recent collisions experienced in theasteroid belt. In such a hypervelocity collision, the smaller collisionpartner is destroyed, whereas a crater on the asteroid is formed or itis entirely ...
A study on meteor head echo using a probabilistic detection model at Jicamarca
(American Geophysical Union, 2020-01)
A coded long pulse is applied to the Jicamarca 50 MHz high power large aperture radar to study meteor head echoes. We develop a probabilistic detection model, which finds 25% more meteors than the commonly used signal‐to‐noise ...
Cruces y capturas de asteroides en la resonancia de movimientos medios 3:1 con Júpiter por efecto Yarkovsky
(2011-02-25)
La resonancia de movimientos medios 3:1 con Júpiter es el límite entre el cinturón de asteroides interno y el intermedio, la cual se encuentra asociada a una de las más importantes lagunas de Kirkwood. El fuerte caos que ...
Meteor-head echo observations using an antenna compression approach with the 450 MHz Poker Flat Incoherent Scatter Radar
(Elsevier, 2009-05)
In this work we present a novel use of the Poker Flat Incoherent Scatter Radar (PFISR) to study meteor-head echoes with wide (W) beams. Until now, most of the meteor-head echo studies have been performed with High-Power ...
