Design and simulation of a photonic lantern-inspired astrophotonic chip for spectral sensing
Avi Patel, Kevin A. Bundy, Aditya Sengupta +10
Compact astrophotonic sensors can trade general-purpose spectral coverage for task-specific wavelength discrimination in a small integrated footprint. Developed with the Mazin Lab…
JWST COMPASS Program: The 3--5m transmission spectrum of LTT 1445 A b
Natasha E. Batalha, Nicole Wallack, Tyler Gordon +16
The search for an atmosphere on the closest rocky M dwarf planet, LTT 1445 A b, has been the subject of intense investigation from both the ground and space. Here, we present the f…
JWST COMPASS: A NIRSpec G395H Transmission Spectrum of Radius Valley-Dweller TOI-260 b
Annabella Meech, Peter Gao, Nicole L. Wallack +16
We present a JWST/NIRSpec G395H transmission spectrum of TOI-260 b, a K, planet. The transmission spectrum is derived by com…
JWST COMPASS: NIRSpec/G395H Transmission Observations of the Sub-Neptune HD 15337 c
Nicole L. Wallack, Peter Gao, Michael Greklek-McKeon +17
We present the 3-5 m transmission spectrum of HD 15337 c (TOI-402.02), a sub-Neptune (2.526 R, 6.792 M, T656 K) around a K1V star observe…
JWST COMPASS: Insights into the Systematic Noise Properties of NIRSpec/G395H From a Uniform Reanalysis of Seven Transmission Spectra
Tyler A. Gordon, Natalie M. Batalha, Natasha E. Batalha +9
JWST has already observed near-infrared transmission spectra of over a dozen super-Earths and sub-Neptunes. While some observations have allowed astronomers to characterize sub-Nep…
JWST COMPASS: A NIRSpec G395H Transmission Spectrum of the Super-Earth GJ 357 b
Jea Adams Redai, Nicholas Wogan, Nicole L. Wallack +14
We present JWST NIRSpec/G395H transmission spectroscopy observations of GJ 357 b, a warm ( K) super-Earth (, $1.84\ \mathrm{…
