Zusammenfassung: | MagAO-X is the coronagraphic extreme adaptive optics system for the 6.5 m
Magellan Clay Telescope. We report the results of commissioning the first phase
of MagAO-X. Components now available for routine observations include: the >2
kHz high-order control loop consisting of a 97 actuator woofer deformable
mirror (DM), a 2040 actuator tweeter DM, and a modulated pyramid wavefront
sensor (WFS); classical Lyot coronagraphs with integrated low-order (LO) WFS
and control using a third 97-actuator non-common path correcting (NCPC) DM;
broad band imaging in g, r, i, and z filters with two EMCCDs; simultaneous
differential imaging in H-alpha; and integral field spectroscopy with the VIS-X
module. Early science results include the discovery of an H-alpha jet, images
of accreting protoplanets at H-alpha, images of young extrasolar giant planets
in the optical, discovery of new white dwarf companions, resolved images of
evolved stars, and high-contrast images of circumstellar disks in scattered
light in g-band (500 nm). We have commenced an upgrade program, called "Phase
II", to enable high-contrast observations at the smallest inner working angles
possible. These upgrades include a new 952 actuator NCPC DM to enable
coronagraphic wavefront control; phase induced amplitude apodization
coronagraphs; new fast cameras for LOWFS and Lyot-LOWFS; and real-time computer
upgrades. We will report the status of these upgrades and results of first
on-sky testing in March-May 2024. |
