Cluster dynamics largely shapes protoplanetary disc sizes

open access: yes, 2016
It is still on open question to what degree the cluster environment influences the sizes of protoplanetary discs surrounding young stars. Particularly so for the short-lived clusters typical for the solar neighbourhood in which the stellar density and ...

Defects in Inorganic Mechanoluminescent Phosphors: Insights and Impacts

open access: yesAdvanced Functional Materials, Volume 35, Issue 40, October 1, 2025.
Mechanoluminescence is attracting more attention recently, and defect dominates mechanoluminescence performances. Investigating how defects work in the mechanoluminescence process is crucial for elucidating its complex luminescence mechanism. This review aims to emphasize the fundamental role of defects in mechanoluminescence, which offers an ...

Early supernovae light-curves following the shock-breakout

open access: yes, 2010
The first light from a supernova (SN) emerges once the SN shock breaks out of the stellar surface. The first light, typically a UV or X-ray flash, is followed by a broken power-law decay of the luminosity generated by radiation that leaks out of the ...

The Radial Structure of the Cygnus Loop Supernova Remnant --- Possible evidence of a cavity explosion --- [PDF]

open access: yes, 1999
We observed the North-East (NE) Limb toward the center region of the Cygnus Loop with the ASCA Observatory. We found a radial variation of electron temperature (kTe) and ionization timescale (log(\tau)) whereas no variation could be found for the ...

La experiencia española de la banca emisora: la pluralidad de emisión en el siglo XIX*

open access: yesEl Trimestre Económico
En las décadas centrales del siglo XIX, España desarrolló un sistema bancario basado en la pluralidad de emisión. Diversos bancos fueron autorizados por el Estado para hacer circular sus billetes en sus respectivas provincias. Este proceso dio lugar a un

Gamma-ray Emission from Crushed Clouds in Supernova Remnants

open access: yes, 2010
It is shown that the radio and gamma-ray emission observed from newly-found "GeV-bright" supernova remnants (SNRs) can be explained by a model, in which a shocked cloud and shock-accelerated cosmic rays (CRs) frozen in it are simultaneously compressed by

Star formation triggered by SN explosions: an application to the stellar association of $\beta$ Pictoris [PDF]

open access: yes, 2006
In the present study, considering the physical conditions that are relevant in interactions between supernova remnants (SNRs) and dense molecular clouds for triggering star formation we have built a diagram of SNR radius versus cloud density in which the
