AaLLM: An End-to-End Analog Circuit Design Framework from Topology Generation to Sizing Using Large Language Models

Mohammed Ayman Habib, Rylan Hart, Morteza Fayazi

Analog circuit design is a time-consuming, iterative process in a nonlinear and high-dimensional design space that relies heavily on expert intuition. Among recent developments, LL…

Mitigating Charge Migration in JWST NIRISS Reveals That KELT-7 b is a Metal-enriched Ultra-hot Jupiter Orbiting a Young Metal-rich Star

Stephen P. Schmidt, Erin M. May, Joshua D. Lothringer +19

We present the first panchromatic JWST transmission spectrum of an ultra-hot Jupiter, combining NIRISS and NIRSpec observations to constrain KELT-7\,b's atmospheric properties. We…

Cloudy mornings and clear evenings on a gas giant exoplanet

Sagnick Mukherjee, David K. Sing, Guangwei Fu +25

The spectra of exoplanet atmospheres are affected by aerosols (clouds and hazes) of uncertain origin. Proposed aerosol formation mechanisms include gas condensation or photochemica…

BOWIE-ALIGN: Weak spectral features in KELT-7b's JWST NIRSpec/G395H transmission spectrum imply a high cloud deck or a low-metallicity atmosphere

Eva-Maria Ahrer, Charlotte Fairman, James Kirk +20

Hot Jupiters and their atmospheres are prime targets for transmission spectroscopy due to their extended atmospheres and the corresponding large signal-to-noise, providing the best…

Modeling tails of escaping gas in exoplanet atmospheres with Harmonica

Carlos Gascón, Mercedes López-Morales, Shreyas Vissapragada +5

Exoplanets that reside close to their host stars, and therefore receive substantial amounts of X-ray and ultraviolet radiation, are prone to suffer from strong atmospheric escape.…

Overcast mornings and clear evenings in hot Jupiter exoplanet atmospheres

Guangwei Fu, Sagnick Mukherjee, Kevin B. Stevenson +10

Aerosols is an old topic in the young field of exoplanet atmospheres. Understanding what they are, how they form, and where they go has long provided a fertile playground for theor…
