Extreme AO correction in the NIR region with SR > 95% best PSF subtraction with or without coronagraph increasing target S/N.
Very good SR > 40% in the optical R-I bands new window for high angular resolution (~17 mas) at a single telescope, comparable to what achievable at LBT by NIR interferometry.
Contrast < 10-4
H band w/o coronograph
Why SHARK
SHARK is the VIS & NIR coronographic imager that will make use of the LBT excellent AO performances!

Direct imaging of close giant planets investigating the main evolutionary stages:
Young planets, from early phases of growth (the first few million years) when these are hot, surrounded by disks, and can be revealed thermally at T> 300 K in NIR and in Halpha (VIS channel)
Old giant planets, very close (< 5-10 pc ) and bright, whose reflected light could be detected for separations of the order of 100-200 mas in the visible, where greater is their emission, and also in the NIR if very cloudy.
Disks around Young Stars and their Jets
High-contrast images of circumstellar disks with optical/near-IR coronagraphy and polarimetric differential imaging

What is SHARK?
• Initial idea:
• Essentially a Coronagraphic camera, working from R to K bands (designed
for high contrast imaging)
• The basic idea is to make it simple as possible (compact, light, close to the
WFS) and cheap
• The baseline coronagraphic technique is classical Lyot
• Several designs initially considered (in the SHARK proposal submitted for
the call for ideas for 2nd generation LBT instrumentation - October 2012)
5 11/11/2014 3:06 PM SHARK-NIR@LBT - Pianeti Extrasolari - Roma
Even if it is a 2nd generation instrument, it can coexist with the 1st generation, with an impact as soft as possible (simplicity, small dimension, only partially overlapping wavelength range).
In fact, SHARK basic features are:
NIR Coro-Camera (J,H,K)
VIS Coro-Camera (R,I)
VIS Spectrograph

Coronagraphy
• There is a baseline design for the coronagraph (Classical
Lyot), but we do have a flexible design with filter wheels
on both the focal and the pupil planes, where different
techniques might be implemented

SHARK-NIR Schedule Milestones
On request of LBT Board, SHARK-NIR is a fast track project with a very aggressive (success oriented!) schedule (which supposes a certain cash flow), the main milestones of which are:
Estimated T0 in January 2015
Conceptual Design Review in T0 + 5m (May 2015)
Final Design Review in T0 + 14m (February 2016)
NIR Camera for Direct Imaging on SKY in about 2.5-3 years from T0 (Fall 2017)
NIR CORO mode on Sky in about 3.5 years from T0 (Mid 2018)

Statement on Open Use
We intend SHARK to be a facility instrument, and
thus to offer it to the whole LBTO community,
beyond the partners involved in our proposal.

cases which require binocularity and coronagraphy (we did not touch the NON-Coro and the single eye science)
