All in the Family: Upcoming Changes in the LCDB
Abstract
Since 2005, the asteroid lightcurve database (LCDB; Warner et al., 2009) used osculating orbital elements to assign family/group membership. Including special subgroups, e.g., inner main-belt (MB-I) versus inner main-belt comets (MB-IC), there were fewer than 33 families/groups. The LCDB release expected in 2021 April or May, will incorporate families defined by Nesvorny et al. (2015; Nesvorny, 2015) and additional families defined on the AstDys web site. The change will include revised default albedo and phase slope parameter (G on H-G system) values for each family. In addition, the LCDB will include provisions for data on the H-G12 or H-G1G2 system (Muinonen et al., 2010), which has been formally adopted by the International Astronomical Union. The details of these changes are explained here.
