Maximum likelihood inference for a class of discrete-time Markov-switching time series models with multiple delays
José A. Martínez-Ordóñez, Javier López-Santiago, Joaquín Miguez
Autoregressive Markov switching (ARMS) time series models are used to represent real-world signals whose dynamics may change over time. They have found application in many areas of…
Adaptive quadrature schemes for Bayesian inference via active learning
F. Llorente, L. Martino, V. Elvira +2
Numerical integration and emulation are fundamental topics across scientific fields. We propose novel adaptive quadrature schemes based on an active learning procedure. We consider…
The Gaia-ESO Survey: kinematical and dynamical study of four young open clusters
L. Bravi, E. Zari, G. G. Sacco +32
Context. The origin and dynamical evolution of star clusters is an important topic in stellar astrophysics. Several models have been proposed to understand the formation of bound a…
Formation of X-ray emitting stationary shocks in magnetized protostellar jets
S. Ustamujic, S. Orlando, R. Bonito +3
X-ray observations of protostellar jets show evidence of strong shocks heating the plasma up to temperatures of a few million degrees. In some cases, the shocked features appear to…
Modeling non-thermal emission from stellar bow shocks
V. Pereira, J. López-Santiago, M. Miceli +2
Runaway O- and early B-type stars passing throughout the interstellar medium at supersonic velocities and characterized by strong stellar winds may produce bow shocks that can serv…
XMM-Newton and Chandra observations of G272.2-3.2. Evidence of stellar ejecta in the central region
E. Sánchez-Ayaso, J. A. Combi, F. Bocchino +4
We aim to study the spatial distribution of the physical and chemical properties of the X-ray emitting plasma of the supernova remnant G272.2-3.2, in order to get important constra…
A sparse population of young stars in Cepheus
A. Klutsch, D. Montes, P. Guillout +5
Once mixed in the ambient galactic plane stellar population, young stars are virtually indiscernible because neither their global photometric properties nor the presence of nearby…
X-ray optical depth diagnostics of T Tauri accretion shocks
C. Argiroffi, A. Maggio, G. Peres +4
In classical T Tauri stars, X-rays are produced by two plasma components: a hot low-density plasma, with frequent flaring activity, and a high-density lower temperature plasma. The…
X-ray flares on the UV Ceti-type star CC Eridani: a "peculiar" time-evolution of spectral parameters
I. Crespo-Chacón, G. Micela, F. Reale +3
Context: Weak flares are supposed to be an important heating agent of the outer layers of stellar atmospheres. However, due to instrumental limitations, only large X-ray flares hav…
