The exploration of the sub-stellar regime via direct imaging, hampered so far by technical limitations, is starting to provide us with a powerful tool. SPHERE at VLT, combining extreme adaptive optics with coronagraphy, dual-band imaging and integral field spectroscopy, has started its operations: relatively massive exoplanets at few tenths of arcsecond separations and contrasts better than 10^6 can be reached.In this contribution I will present recent results obtained with SPHERE in the framework of the SHINE survey. Moreover, I will present a new system for coronagraphy with high-order adaptive optics that will be operating at LBT by the end of 2019: SHARKs. This system will provide coronagraphic observations from visual to NIR bands, allowing a spectral coverage that is not currently available for any other instrument in the world. Finally, I will discuss the employment of a brand-new technique that combines high-contrast imaging with high-dispersion spectroscopy, allowing in principle to reach contrasts down to 10^10. In the era of ELTs, this will open the way to investigating earth-like planets in the habitable zones of their parent stars.<\/p>\n","protected":false},"template":"","class_list":["post-4549","seminari","type-seminari","status-publish","hentry","categorie_seminari-colloquium"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.oa-cagliari.inaf.it\/en\/wp-json\/wp\/v2\/seminari\/4549","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.oa-cagliari.inaf.it\/en\/wp-json\/wp\/v2\/seminari"}],"about":[{"href":"https:\/\/www.oa-cagliari.inaf.it\/en\/wp-json\/wp\/v2\/types\/seminari"}],"wp:attachment":[{"href":"https:\/\/www.oa-cagliari.inaf.it\/en\/wp-json\/wp\/v2\/media?parent=4549"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
