RHESSI limb observations
H. S. Hudson
University of California, Berkeley
Ways to peer inside the Sun
• Theory: Hoyle; Bahcall
• Irradiance variability
• Shape and location of limb (RHESSI)
• Gravity
• Helioseismology
• New NASA program: solar core penetrator mission, featuring sample return

What to do next?
• Continue characterization of data and weeding-out of systematic variations
• Studies of activity-related limb features (ARs, flares, prominences)
• Studies of shape (harmonic terms)
• Oscillations (p-modes for sure; g-modes -?-in collaboration with Quataert)
