Integrated optics for astronomical interferometry - VI. Coupling the light of the VLTI in K band [PDF]

, 2005
Our objective is to prove that integrated optics (IO) is not only a good concept for astronomical interferometry but also a working technique with high performance.

Stellar Intensity Interferometry: Astrophysical targets for sub-milliarcsecond imaging [PDF]

, 2010
Intensity interferometry permits very long optical baselines and the observation of sub-milliarcsecond structures. Using planned kilometric arrays of air Cherenkov telescopes at short wavelengths, intensity interferometry may increase the spatial ...

Differential rotation in early type stars [PDF]

, 2006
Using 2D models of rotating stars, the interferometric measurements of alpha Eri and its fundamental parameters corrected for gravitational darkening effects we infer that the star might have a core rotating 2.7 times faster than the surface.

On-sky observations with an achromatic hybrid phase knife coronagraph in the visible [PDF]

, 2006
CONTEXT: The four-quadrant phase mask stellar coronagraph, introduced by D. Rouan et al., is capable of achieving very high dynamical range imaging and was studied in the context of the direct detection of extra-solar planets.

Understanding the impacts of intensity and harvest frequency on Tithonia diversifolia for use in tropical silvopastoral systems

Grassland Science, Volume 71, Issue 4, Page 149-163, October 2025.
Abstract Tithonia diversifolia (Hemsl.) A. Gray has significant potential as a forage source in silvopastoral systems, particularly in tropical conditions. However, its intensity and frequency management differ from those commonly applied to grasses. This study aims to evaluate T. diversifolia under two harvest intensities (30 and 40 cm stubble height)

Late Stages of Tropical Silvopastoral System: An Opportunity to Maximise Forage and Animal Production

Grass and Forage Science, Volume 80, Issue 3, July-September 2025.
ABSTRACT Silvopastoral systems (SPS) integrate pasture, trees, and animals in the same area and are alternatives for sustainable pasture intensification. We aimed to test whether, in the late stages of an SPS, with large but sparsely distributed trees (83 trees ha−1), forage and animal productivity are comparable to a full sun pasture (FS) over an ...

Pulsations as a mass-loss trigger in evolved hot stars

, 2013
During the post-main sequence evolution massive stars pass through several short-lived phases, in which they experience enhanced mass loss in the form of clumped winds and mass ejection events of unclear origin.

Structural and productive responses of signalgrass and its association with leaf area index and light interception under silvopastoral or monoculture systems

Agrosystems, Geosciences &Environment, Volume 8, Issue 2, June 2025.
Abstract Silvopastoral systems (SPSs) have emerged as one of the most prominent alternatives for grassland recovery. We evaluated the structural and productive responses of signalgrass [Urochloa decumbens (Stapf.) R. D. Webster] and its association with leaf area index (LAI) and light interception (LI) measured with different equipment across different
