4 Dec 2018 | | Abstract: | Making an inventory of the Solar System is one of the four fundamental
science requirements for the Large Synoptic Survey Telescope (LSST). The
current baseline footprint for LSST’s main Wide-Fast-Deep (WFD) Survey observes
the sky below 0$^circ$ declination, which includes only half of the ecliptic
plane. Critically, key Solar System populations are asymmetrically distributed
on the sky: they will be entirely missed, or only partially mapped, if only the
WFD occurs. We propose a Northern Ecliptic Spur (NES) mini survey, observing
the northern sky up to +10$^circ$ ecliptic latitude, to maximize Solar System
science with LSST. The mini survey comprises a total area of $sim$5800
deg$^2$/604 fields, with 255 observations/field over the decade, split between
g,r, and z bands. Our proposed survey will 1) obtain a census of main-belt
comets; 2) probe Neptune’s past migration history, by exploring the resonant
structure of the Kuiper belt and the Neptune Trojan population; 3) explore the
origin of Inner Oort cloud objects and place significant constraints on the
existence of a hypothesized planet beyond Neptune; and 4) enable precise
predictions of KBO stellar occultations. These high-ranked science goals of the
Solar System Science Collaboration are only achievable with this proposed
northern survey. | | Source: | arXiv, 1812.1149 | | Services: | Forum | Review | PDF | Favorites | |
