		gs. Ground based surveys are not optimal for this type of photom
		etric variability study due to large amounts of observing time r
		equired & nightly aliasing effects on lightcurves. Kepler ho
		wever is ideal for this type of photometric survey of asteroid v
		ariability due to the photometric stability of the observing pla
		tform and the correspondence between the C11 field and the L4 Tr
		ojan cloud. Methodology: We have identified 100 objects for stud
		y in the Hilda and Trojan asteroids to be studied with Kepler in
		 C11-13 with magnitudes of m_V < 20. Due to the overlap betwe
		en the Campaign 11 field and the L4 Trojan cloud, our request fo
		r data represents 70 objects Campaign 11, 23 objects in Campaign
		 12 & 7 objects in Campaign 13. These objects are not statio
		nary within the Kepler fields, rather they move across the field
		, resulting in a mean time in the Kepler field of view on active
		 silicon of 24 days. Due to the motion of these targets, the Kep
		ler Science Center assesses solar system program as containing m
		ore targets than proposed number of objects, (In C8, 6 Hilda tar
		gets are assessed as 4847 targets by the Kepler Science Center),
		 thus THIS PROPOSAL SHOULD BE CONSIDERED A LARGE PROPOSAL. We wi
		ll utilize data obtained with the 30 minute Kepler cadence to de
		termine rotational periods for our selected targets. The ratio o
		f lightcurve amplitudes will subsequently be utilized to determi
		ne body elongation and/or binarity.Relevance to K2:This study wi
		ll obtain high fidelity lightcurves for solar system objects in 
		the Kepler field of view during campaigns 11-13  to determine if
		 these objects originated in the Kuiper Belt and later migrated 
		and are amenable to the operational characteristics and constrai
		nts of the mission and defined observing fields.}
