JWST COMPASS: NIRSpec/G395H Transmission Observations of the Sub-Neptune HD 15337 c

We present the 3–5 μ m transmission spectrum of HD 15337 c (TOI-402.02), a sub-Neptune (2.526 R _⊕ , 6.792 M _⊕ , T _eq ∼ 656 K) around a K1V star observed as part of the JWST COMPASS program. We reduce two observations with two pipelines and find consistent transmission spectra. The resulting media...
