Building Reliable Models of M Dwarf Chromospheres: The Spectral Diagnostics [PDF]
, 2000 As part of an ongoing project to study how reliable are the chromospheric models constructed semiempirically to fit the chromospheric spectrum of cold stars, in this paper we study how changes in the assumed chromospheric structure of dM and dMe stars ...

Holographic interference in atomic photoionization from a semiclassical standpoint [PDF]
, 2019 A theoretical study of the interference pattern imprinted on the doubly differential momentum distribution of the photoelectron due to atomic ionization induced by a short laser pulse is developed from a semiclassical standpoint. We use the semiclassical

Pulsed Laser Ablation in Liquid: Numerical Evaluation of Laser Fluence
physica status solidi (RRL) – Rapid Research Letters, Volume 19, Issue 12, December 2025.Pulsed laser ablation in liquid is a very powerful technique that allows to synthesize colloidal solution of nanoparticles (NPs) without waste. Herein, a computational approach that given the experimental parameters and draws the laser ray paths inside the experimental apparatus is developed, the effective fluence on the target surface is evaluated ...

Journal of Metamorphic Geology, Volume 43, Issue 9, Page 863-890, December 2025.ABSTRACT Orogenic belts that sustain elevated temperatures at intermediate crustal depths for tens of millions of years are known as hot orogens. The evolution of these hot orogens is largely influenced by thermal maturation, primarily driven by the distribution of heat‐producing elements (HPEs), such as K, Th and U in the overthickened crust.

Dust properties in NGC 6611 [PDF]
, 2000 An investigation on dust properties in the NW portion of NGC 6611 has been conducted polarimetrically to test the existence of abnormal extinction in that section of the open cluster in an independent way. As previously suggested for the η Carinae nebula

Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.Abstract We present a multiscale seismic attenuation tomography of a seismotectonically complex region in northern Italy hosting the well‐characterized Collalto Underground Gas Storage (UGS). Beyond its specific relevance, this site provides a natural laboratory for assessing the ability of attenuation imaging to distinguish fluid‐rich zones from ...

Analysis of large scale MHD quantities in expanding magnetic clouds [PDF]
, 2008 Magnetic clouds (MCs) transport the magnetic flux and helicity released by the Sun. They are generally modeled as a static flux rope traveling in the solar wind, though they can present signatures of expansion. We analyze three expanding MCs using a self-

Low‐Energy Atomic Scattering: S‐Wave Relation Between the Interaction Potential and the Phase Shift
Annalen der Physik, Volume 537, Issue 11, November 2025.The validity of the on‐shell approximation for s‐wave scattering is examined across one, two, and three dimensions using exactly solvable model interaction potentials. By comparing exact and approximate s‐wave components of the interaction potential, the analysis reveals that the approximation improves with increasing momentum and decreasing ...
