New Arabic Records From Cairo on Supernovae 1181 and 1006

open access: yesAstronomische Nachrichten, Volume 346, Issue 9, November 2025.
ABSTRACT The remnant of the historical supernova SN 1181 is under discussion: While the previously suggested G130.7+3.1 (3C58) appears too old (3000–5000 year), the unusual star IRAS00500+6713 with a surrounding nebula (Pa‐30) has an expansion age not inconsistent with a SN Iax explosion in ad 1181 under the assumption that neither acceleration nor ...

Using Pleiades Satellite Imagery to Monitor Multi-Annual Coastal Dune Morphological Changes

open access: yesRemote Sensing
In the context of sea levels rising, monitoring spatial and temporal topographic changes along coastal dunes is crucial to understand their dynamics since they represent natural barriers against coastal flooding and large sources of sediment that can ...

A New Pleiades Member at the Lithium Substellar Boundary

open access: yes, 1998
We present the discovery of an object in the Pleiades open cluster, named Teide 2, with optical and infrared photometry which place it on the cluster sequence slightly below the expected substellar mass limit.

Spitzer 24 micron Survey of Debris Disks in the Pleiades [PDF]

open access: yes, 2006
We performed a 24 micron 2 Deg X 1 Deg survey of the Pleiades cluster, using the MIPS instrument on Spitzer. Fifty four members ranging in spectral type from B8 to K6 show 24 micron fluxes consistent with bare photospheres.

Large‐Scale Topographic Changes at Erupting Volcanoes Measured by the TanDEM‐X Digital Change Map

open access: yesEarth and Space Science, Volume 12, Issue 11, November 2025.
Abstract Volcanic eruptions cause large‐scale topographic changes, through the emplacement of lava flows and lava domes, the formation of craters and calderas, and thick ash and pyroclastic deposits. Here we analyze the TanDEM‐X Digital Change Map (DCM), which compares the DEM produced during 2010–2015 with satellite acquisitions collected in 2016–2022.

Réalisation du RGE Alti en zone de montagnes à partir d'images Pléiades

open access: yesRevue Française de Photogrammétrie et de Télédétection, 2014
La référence altimétrique nationale, nommée RGE Alti, est actuellement composée de données issues de traitements Radar sur les zones de montagne qui ne satisfont pas pleinement les spécifications.

Pre-main-sequence isochrones -- I. The Pleiades benchmark [PDF]

open access: yes, 2012
We present a critical assessment of commonly used pre-main-sequence isochrones by comparing their predictions to a set of well-calibrated colour-magnitude diagrams of the Pleiades in the wavelength range 0.4 to 2.5 microns.

Small‐Scale, High‐Frequency Ice, and Ocean Processes in the Amundsen Sea Embayment, West Antarctica

open access: yesJournal of Advances in Modeling Earth Systems, Volume 17, Issue 11, November 2025.
Abstract In proximity of the Antarctic ice sheet, oceanic motions with different spatial structures contribute to the transport of warm water onto the continental shelf, fueling submarine ice‐shelf melting. Emerging evidence suggests that km‐sized ocean submesoscale fronts and eddies significantly impact ice‐ocean interactions on timescale of a few ...

Peculiarities of «liquid – solid» phase equilibria in Six-Ge1-x nanoparticles for various mutual arrangements of phases

open access: yesФизико-химические аспекты изучения кластеров, наноструктур и наноматериалов
The application of 3D nanocrystalline materials obtained using the liquid-phase and solid-phase powder metallurgy technologies is one of the basic approaches to designing high-efficiency and low-cost thermoelectric energy converters.
