Atmosphere, 2023 We explored spectral diversity in infrared (IR, 4–25 μm) imaginary (k) and real (n) indices of refraction (optical constants) for 26 surface soils that originated from global dust entrainment regions.

Transmission spectra of sausage-like microresonators
Optics Express, 2015 We experimentally develop a sausage-like microresonator (SLM) by making two microtapers on a single-mode fiber, and study whispering-gallery modes (WGMs) in SLMs with different lengths. The transmission spectra from 1530 nm to 1550 nm of several SLMs are presented and SLMs with different lengths are shown to have different transmission features.

On Degeneracies in Retrievals of Exoplanetary Transmission Spectra
The Astronomical Journal, 2019 Abstract Accurate estimations of atmospheric properties of exoplanets from transmission spectra require the understanding of degeneracies between model parameters and observations that can resolve them. We conduct a systematic investigation of such degeneracies using a combination of detailed atmospheric retrievals and a range of model ...

The Featureless Transmission Spectra of Two Super-puff Planets [PDF]
The Astronomical Journal, 2020 Abstract The Kepler mission revealed a class of planets known as “super-puffs,” with masses only a few times larger than Earth’s but radii larger than Neptune, giving them very low mean densities. All three of the known planets orbiting the young solar-type star Kepler 51 are super-puffs.

Aurora: A Generalized Retrieval Framework for Exoplanetary Transmission Spectra [PDF]
The Astrophysical Journal, 2021 Abstract Atmospheric retrievals of exoplanetary transmission spectra provide important constraints on various properties, such as chemical abundances, cloud/haze properties, and characteristic temperatures, at the day–night atmospheric terminator.
