Preferential Appearance of Hα Moreton Waves along Photospheric Magnetic Network Boundaries

The Astrophysical Journal Letters
Moreton waves are rare chromospheric signatures of large-scale coronal disturbances, often associated with big flares and coronal mass ejections. Using high-cadence, full-disk H α spectroscopic observations from Chinese H α Solar Explorer, together with ...

Quartz Clouds in the Dayside Atmosphere of the Quintessential Hot Jupiter HD 189733 b

The Astrophysical Journal Letters
Recent mid-infrared observations with JWST's Mid-Infrared Instrument Low Resolution Spectrometer (MIRI LRS) have resulted in the first direct detections of absorption features from silicate clouds in the transmission spectra of two transiting exoplanets,

Industry structure and collusion with uniform yardstick competition: theory and experiments [PDF]

, 2014
We study cartel stability in an industry that is subject to uniform yardstick regulation. In a theoretical model, we show that the number of symmetric firms does not affect collusion. In a laboratory experiment, however, we do find an effect. If anything,

Two-dimensional Radiation-hydrodynamic Simulations of Luminous Red Novae

The Astrophysical Journal Letters
Luminous red novae (LRNe) are transients associated with mass ejection during stellar mergers and common envelope evolution (CEE). LRNe have the potential to illuminate the poorly understood phases of binary evolution leading up to the CEE, during the ...

Electromagnetic Signatures from Pulsar Remnants of Binary Neutron Star Mergers: Prospects for Unique Identification Using Multiwavelength Signatures

The Astrophysical Journal Letters
Binary neutron star (BNS) mergers can result in the formation of long-lived magnetar remnants that can enhance neutrino and electromagnetic (EM) emissions.

Most High-density Exoplanets Are Unlikely to Be Remnant Giant Planet's Cores

The Astrophysical Journal Letters
Some exoplanets have much higher densities than expected from stellar abundances of planet-forming elements. There are two theories—metal-rich formation hypothesis and naked core hypothesis—that explain how formation and evolution can alter the ...

Optimisation et caractérisation de nouveaux inhibiteurs pharmacologiques de DYRKs et CLKs, les leucettines

, 2013
Les DYRKs (dual specificity, tyrosine phosphorylation regulated Kinases) et CLKs (cdc2-like kinases) sont deux familles de kinases du groupe CMGC. Elles sont impliquées dans le développement de la maladie d'Alzheimer et de la trisomie 21. Nous présentons
