Automatic generation of electro-thermal models with TRAPPIST

2014 21st IEEE International Conference on Electronics, Circuits and Systems (ICECS), 2014
It has been shown that the transfer function trajectories (TFT) approach allows the automated extraction of compact behavioral models for analog and mixed-signal circuit blocks. The models consist in the concatenation of a multiple-input-multiple-output (MIMO) linear filtering stage and a nonlinear scheduling stage, ensuring a very broad coverage for ...

Molecular Hydrogen Controls the Temperatures of Flares on TRAPPIST-1

Astrophysical Journal Letters
Early JWST observations of TRAPPIST-1 have revealed an unexpected puzzle: energetic white-light flares (E > 1030 erg) reach temperatures of only ∼3500–4000 K, nearly 3 times cooler than typical solar flares, which peak around 9000–10,000 K.

The TRAPPIST comet survey

2014
TRAPPIST (TRAnsiting Planets and PlanetesImals Small Telescope) is a 60-cm robotic telescope that has been installed in June 2010 at the ESO La Silla Observatory [1]. Operated from Liège (Belgium) it is devoted to the detection and characterisation of exoplanets and to the study of comets and other small bodies in the Solar System. We describe here the

Higher-order Mean-motion Resonances Can Form in Type I Disk Migration

Astrophysical Journal
Type I disk migration can form a chain of planets engaged in first-order mean-motion resonances (MMRs) parked at the disk inner edge. However, while second- or even third-order resonances were deemed unlikely due to their weaker strength, they have been ...

Ionic emission from and activity evolution in comet C/2020 F3 (NEOWISE): Insights from long-slit spectroscopy and photometry

Astronomy & Astrophysics
The long-period comet C/2020 F3 (NEOWISE) was the brightest comet in the northern hemisphere since C/1995 O1 (Hale-Bopp). These comets offer a unique opportunity to study their composition and the spatial variation in the different emission in detail. We

Flares on TRAPPIST-1 Reveal the Spectrum of Magnetic Features on Its Surface

Astrophysical Journal Letters
TRAPPIST-1 is an M8 dwarf hosting seven known exoplanets and is currently one of the most frequently observed targets of the James Webb Space Telescope (JWST).
