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…
On the Potential of Spectroastrometry with Photonic Lanterns
Yoo Jung Kim, Michael P. Fitzgerald, Jonathan Lin +5
We investigate the potential of photonic lantern (PL) fiber fed spectrometers for two-dimensional spectroastrometry. Spectroastrometry, a technique for studying small angular scale…
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…
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…
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…
Coherent Imaging with Photonic Lanterns
Yoo Jung Kim, Michael P. Fitzgerald, Jonathan Lin +4
Photonic Lanterns (PLs) are tapered waveguides that gradually transition from a multi-mode fiber geometry to a bundle of single-mode fibers (SMFs). They can efficiently couple mult…
The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems V: Do Self-Consistent Atmospheric Models Represent JWST Spectra? A Showcase With VHS 1256 b
Simon Petrus, Niall Whiteford, Polychronis Patapis +119
The unprecedented medium-resolution (R~1500-3500) near- and mid-infrared (1-18um) spectrum provided by JWST for the young (140+/-20Myr) low-mass (12-20MJup) L-T transition (L7) com…
