A Detailed Investigation of HD 209458 b HST and JWST Transmission Spectra with SANSAR

The Astronomical Journal
HD 209458 b is the first exoplanet on which an atmosphere was detected. Since then, its atmosphere has been investigated using multiple telescopes and instruments. However, many of its atmospheric constraints remain debatable.

HST SHEL: Revealing Haze and Confirming Elevated Metallicity in the Warm Neptune HAT-P-26b

The Astronomical Journal
We present a new and extended transmission spectrum of the warm Neptune HAT-P-26b spanning wavelengths between 0.29 and 5.0 μ m. This spectrum is derived from new HST STIS G430L observations from the PanCET program, a reanalysis of the previously ...

MOFs and COFs in Electronics: Bridging the Gap between Intrinsic Properties and Measured Performance

Advanced Functional Materials, EarlyView.
Metal‐organic frameworks (MOFs) and covalent organic frameworks (COFs) hold promise for advanced electronics. However, discrepancies in reported electrical conductivities highlight the importance of measurement methodologies. This review explores intrinsic charge transport mechanisms and extrinsic factors influencing performance, and critically ...

Probing Two-dimensional Asymmetries of an Exoplanet Atmosphere from Chromatic Transit Variation

The Astronomical Journal
We propose a new method for investigating atmospheric inhomogeneities in exoplanets through transmission spectroscopy. Our approach links chromatic variations in conventional transit model parameters—central transit time, total and full durations, and ...

Rapid Sintering of Porous Organic Polymer Powders Into Mechanically Strong Monoliths for Efficient CO2 Capture

Advanced Functional Materials, EarlyView.
Spark plasma sintering enables rapid processing of porous organic polymer (POP) from fine powders to a freestanding and mechanically robust monolith. The sintering process retains the CO2 adsorption capacity and CO2/N2 selectivity, making the monolith more suitable as a solid sorbent for practical carbon capture applications.

Reliable Transmission Spectrum Extraction with a Three-parameter Limb-darkening Law

The Astrophysical Journal Letters
Stellar limb darkening must be properly accounted for to accurately determine the radii of exoplanets at various wavelengths. The standard approach to address limb darkening involves either using laws with coefficients from modeled stellar spectra or ...
