Sensitivity of Spectral Lines to Granulation: The Sun
The Astrophysical JournalThe intrinsic variability of stars, due to acoustic oscillations, surface granulation, and magnetic activity, introduces radial velocity (RV) jitter in spectral lines, obscuring true planetary signals and hindering the detection of Earth-like planets ...

Helioseismic evidence of two solar granulation timescales
, 2005 The signature of two different scales of solar granulation in the power spectrum of disk integrated irradiance time series is presented. The fitted timescales for granulation ($\tau_{{\rm GR1}}\approx 237~{\rm s}$ and $\tau_{{\rm GR2}}\approx 62~{\rm ...

Food and Energy Security, Volume 15, Issue 5, September/October 2026.ABSTRACT The development of enhanced fertilizers using amino acid‐based biostimulants can help improve fertilizer use efficiency and reduce environmental emissions. However, in the context of phosphorus (P) risk management, the potential physiological mechanisms by which amino acid enhanced P fertilizers affect maize yield and P use efficiency (PUE ...

Evolution of solar granulation fields from THEMIS-IPM time series [PDF]
, 2002 The temporal evolution of solar granulation has been investigated using a time series of high spatial and spectral resolution images acquired at the THEMIS solar telescope (Observatorio del Teide, Tenerife) using the IPM observing mode.

Epidermoid cyst as differential diagnosis for spherical keratoma: What do we know?
Equine Veterinary Education, Volume 38, Issue 9, Page 489-508, September 2026.Summary This article briefly presents the case of a space‐occupying coronary band mass that raised the question of how one can differentiate between two uncommonly seen but now commonly paired differential diagnoses and prompted a review of the relevant literature.

Transactions of the International Astronomical Union, 1985 During the period 1981-1984, major developments have been made in the analysis of the shape and shifts of photospheric lines used as a diagnostic of the convection in the outer layers of the Sun. The first three-dimensional numerical simulation of the solar granulation has been developed, and it, is able to reproduce with some success most of the ...

A High-resolution, Inversion-based Synoptic Study of Solar Granulation
The Astrophysical JournalThe convectively driven, weakly magnetized regions of the solar photosphere dominate the Sun’s surface at any given time, but the temporal variations of these quiet regions of the photosphere throughout the solar cycle are still not well known.

Time-dependent appearance of myofibroblasts in granulation tissue of human skin wounds [PDF]
, 1992 Human skin wounds (66) inflicted between 20 h and 7 months prior to biopsy were studied. In order to identify the type of cellular differentiation of the fibroblastic cells in the granulation tissue, alpha-smooth muscle actin and desmin were ...

Granular Spots in the Solar Photosphere
The Astrophysical Journal LettersGranulation and sunspots are fundamental structures of the solar photosphere. Here, we discover the universal dark regions in TiO images from the New Vacuum Solar Telescope and name them granular spots (GSs).
