Title: Nucleus Characterization of Main-Belt Comet P/Read
Abstract:
Main-belt comets (MBCs) are mysterious objects that exhibit cometary
activity yet are dynamically indistinguishable from main-belt asteroids.
Understanding these apparently icy objects so close to the Sun is
important for understanding the distribution of volatile material in our
solar system as well as the origin of Earth's water. Four MBCs are
currently known, though only two have had their nuclei well-
characterized. With so little currently known about this mysterious
population, it is critical that we obtain the best possible physical
characterizations for as many of the currently known MBCs as possible.
This information will aid us in developing a global understanding of the
population's characteristics, such as the level of diversity among
members as well as the level of commonality. In turn, this global
understanding will help answer larger scientific questions such as how
abundant MBCs may be and what implications they have for our
understanding of the distribution of icy bodies in the inner solar
system. We seek observing time on SOAR to develop a definitive physical
characterization of the nucleus of MBC P/2005 U1 (Read). The goals of
our SOAR observations include (but are not limited to) determination of
P/Read's rotation period, nucleus elongation, and colors.
