Spectral characterization of a 3-port photonic lantern for application to spectroastrometry
Yoo Jung Kim, Michael P. Fitzgerald, Jonathan Lin +10
Spectroastrometry, which measures wavelength-dependent shifts in the center of light, is well-suited for studying objects whose morphology changes with wavelength at very high angu…
Visible-Light High-Contrast Imaging and Polarimetry with SCExAO/VAMPIRES
Miles Lucas, Barnaby Norris, Olivier Guyon +17
We present significant upgrades to the VAMPIRES instrument, a visible-light (600 nm to 800 nm) high-contrast imaging polarimeter integrated within SCExAO on the Subaru telescope. K…
Design, scientific goals, and performance of the SCExAO survey for planets around accelerating stars
Mona El Morsy, Thayne Currie, Masayuki Kuzuhara +25
We describe the motivation, design, and early results for our 42-night, 125 star Subaru/SCExAO direct imaging survey for planets around accelerating stars. Unlike prior large surve…
Spectral interferometric wavefront sensing: a solution for petalometry at Subaru/SCExAO
Vincent Deo, Sebastien Vievard, Manon Lallement +12
The petaling effect, induced by pupil fragmentation from the telescope spider, drastically affects the performance of high contrast instruments by inducing core splitting on the PS…
Spectroscopy using a visible photonic lantern at the Subaru telescope: Laboratory characterization and first on-sky demonstration on Ikiiki (α Leo) and `Aua (α Ori)
Sébastien Vievard, Manon Lallement, Sergio Leon-Saval +23
Photonic lanterns are waveguide devices enabling high throughput single mode spectroscopy and high angular resolution. We aim to present the first on-sky demonstration of a photoni…
Astrophotonics -- current capabilities and the road ahead
Barnaby Norris, Simon Gross, Sergio G. Leon-Saval +10
Astrophotonics represents a cutting-edge approach in observational astronomy. This paper explores the significant advancements and potential applications of astrophotonics, highlig…
The GLINT nulling interferometer: improving nulls for high-contrast imaging
Eckhart Spalding, Elizabeth Arcadi, Glen Douglass +13
GLINT is a nulling interferometer downstream of the SCExAO extreme-adaptive-optics system at the Subaru Telescope (Hawaii, USA), and is a pathfinder instrument for high-contrast im…
Visible Photonic Lantern integration, characterization and on-sky testing on Subaru/SCExAO
Sébastien Vievard, Manon Lallement, Sergio Leon-Saval +23
A Photonic Lantern (PL) is a novel device that efficiently converts a multi-mode fiber into several single-mode fibers. When coupled with an extreme adaptive optics (ExAO) system a…
Searching for Protoplanets around MWC 758 and MWC 480 in Br- using Kernel Phase and SCExAO/CHARIS
Alexander Chaushev, Steph Sallum, Julien Lozi +6
Discovering new actively-accreting protoplanets is crucial to answering open questions about planet formation. However, identifying such planets at orbital distances where they are…
Generic data reduction for nulling interferometry package: the grip of a single data reduction package on all the nulling interferometers
Marc-Antoine Martinod, Denis Defrère, Romain Laugier +5
Nulling interferometry is a powerful observing technique to reach exoplanets and circumstellar dust at separations too small for direct imaging with single-dish telescopes and too…
Laboratory demonstration of a Photonic Lantern Nuller in monochromatic and broadband light
Yinzi Xin, Daniel Echeverri, Nemanja Jovanovic +11
Photonic lantern nulling (PLN) is a method for enabling the detection and characterization of close-in exoplanets by exploiting the symmetries of the ports of a mode-selective phot…
Testing magnetospheric accretion as an H emission mechanism of embedded giant planets: The case study for the disk exhibiting meridional flow around HD 163296
Yasuhiro Hasegawa, Taichi Uyama, Jun Hashimoto +7
Recent high-sensitivity observations reveal that accreting giant planets embedded in their parental circumstellar disks can emit H at their final formation stages. While the ori…
