Propiedades físicas de objetos transneptunianos y centauros

Abstract

Esta tesis se ha llevado a cabo en el marco de un programa dedicado al estudio de las propiedades f sicas de objetos transneptunianos y otros cuerpos peque~nos del Sistema Solar, que lleva en curso m as de dos d ecadas en el Instituto de Astrof sica de Andaluc a, con nanciaci on de entidades p ublicas nacionales, auton omicas y europeas. Dentro de este programa se utilizan t ecnicas variadas para el estudio de estos objetos, tanto observacionales como te oricas. Entre ellas, la t ecnica de la fotometr a ha sido una de las herramientas destacadas, en la que el grupo ha hecho un gran n umero de contribuciones cient cas y en la que esta tesis se encuadra. Durante el desarrollo de esta tesis se ha abordado un estudio sistem atico de un conjunto numeroso de objetos, si bien las conclusiones principales han podido derivarse de manera m as concluyente para cuatro de ellos. Los resultados sobre estos objetos han sido publicados en 4 art culos recogidos en esta memoria de tesis, que se presenta en la modalidad de compendio de art culos. An alisis adicionales, as como la preparaci on de las correspondientes publicaciones, se encuentran en desarrollo.

This thesis has been carried out in the frame of a scienti c program devoted to the study of the physical properties of TNOs and other small Solar system bodies that has been running from more than 20 years in the \Instituto de Astrof sica de Andaluc a" (IAA) with funds coming from national, autonomic and european public agencies. Within this program, various observational and theoretical techniques are applied to the study of these objects. Photometric techniques have been one of the most important tools that the group at IAA have been using in order to yield a large number of scienti c contributions. This thesis further applies photometric techniques to the study of TNOs and centaurs. In these four years, a systematic study of a large number of targets has been carried out. The most interesting results that have been extracted from this study have been published in four articles that are included in this dissertation, which is presented as a compendium of papers. Additional (though sometimes partial) results have been obtained for other objects, and further analyses and preparations for their publication are underway.
