Hi Al and List!
Asteroid 6 Hebe is a hot candidate for the H chondrites:
1) GAFFEY M.J. (1996) Spectral identification of asteroid 6 Hebe as the
main-belt parent body of the H-type ordinary chondrites (Meteoritics 31,
1996, A047).
2) GAFFEY M.J. et al. (1998) Asteroid 6 Hebe: The probable parent body
of the H-type ordinary chondrites and the IIE iron meteorites (MAPS
33-6, 1998, 1281).
3) MIGLIORINI F., MANARA A., SCALTRITI F., FARINELLA P., CELLINO A.
and Di MARTINO M. (1997b) Surface properties of 6 Hebe: A possible
parent body of ordinary chondrites (Icarus 128, 104-113).
4) M.E. BENNETT and H.Y.McSWEEN (1996) Revised model calculations
for the thermal histories of ordinary chondrite parent bodies
(Meteoritics 31-6, 1996, 783-792, excerpt from the conclusion chapter):
" ... This result implies significant compaction and thus further
constraints on the radii of the original ordinary chondrite parent
bodies to between 80 and 95 km. This size range matches that of
asteroid 6 Hebe, previously suggested to be an ordinary chondrite
parent body."
Best wishes and good night around the globe,
