Minimal Data Fidelity for Detection of Stellar Features or Companions
Sahil Agarwal, John S. Wettlaufer
Technological advances in instrumentation have led to an exponential increase in exoplanet detection and scrutiny of stellar features such as spots and faculae. While the spots and…
Fluctuations in Arctic Sea Ice Extent: Comparing Observations and Climate Models
Sahil Agarwal, John S. Wettlaufer
The fluctuation statistics of the observed sea ice extent during the satellite era are compared with model output from CMIP5 models using a multi-fractal time series method. The tw…
An intrinsic pink-noise multi-decadal global climate dynamics mode
W. Moon, S. Agarwal, J. S. Wettlaufer
Understanding multi-decadal variability is an essential goal of climate dynamics. For example, the recent phenomenon referred to as the "global warming hiatus" may reflect a coupli…
Sea-Ice Distribution and Mixed-Layer Depths in Fram Strait
Sahil Agarwal, M. Grae Worster
In an effort to understand the dynamics of the Arctic sea-ice edge, we present a simple model of heat and mass transfer in the Fram Strait that reveals some fundamental mechanisms…
Circuit Bounds on Stochastic Transport in the Lorenz Equations
Scott Weady, Sahil Agarwal, Larry Wilen +1
In turbulent Rayleigh-Bénard convection one seeks the relationship between the heat transport, captured by the Nusselt number, and the temperature drop across the convecting layer,…
Exoplanet Atmosphere Retrieval from Multifractal Analysis of Secondary Eclipse Spectra
Sahil Agarwal, John S. Wettlaufer
We extend a data-based model-free multifractal method of exoplanet detection to probe exoplanetary atmospheres. Whereas the transmission spectrum is studied during the primary ecli…
