        "abstract": "We present current status of H\u03b1 high-contrast imaging observations with Subaru/SCExAO+VAMPIRES. Our adaptive optics correction at optical wavelengths in combination with (double) spectral differential imaging (SDI) and angular differential imaging (ADI) was capable of resolving a ring feature around omi Cet and detect the H\u03b1 counterpart of jet around RY Tau. We tested the post-processing by changing the order of ADI and SDI and both of the contrast limits achieved \u223c10\u207b\u00b3 \u2212 5\u00d710\u207b\u2074 at 0.3\", which is comparable to other H\u03b1 high-contrast imaging instruments in the southern hemisphere such as VLT/SPHERE, VLT/MUSE, and MagAO. Current wavefront sensing and adaptive optics correction at optical wavelengths empirically depends on airmass and Subaru/VAMPIRES provides great opportunities for H\u03b1 high-contrast imaging for northern hemisphere targets.",
