Detection of differential rotation in ψ Cap with profile analysis ⋆
We report detection of differential rotation on the F5 dwarf ψ Cap using line profile analysis. The Fourier transform of both Fe i λ5775 and Si i λ5772 are used to obtain a projected rotational velocity of v sin i = 42 ± 1 km s −1. Modelling of the Fourier transformed profiles shows that the combined effects of equatorial velocity, inclination and differential rotation dominate the line profile...
متن کاملWavelet analysis of stellar differential rotation
A key mystery in stellar magnetohydrodynamics is knowledge of stellar differential rotation. At present, the only practical method for detecting the presence of surface differential rotation for slowly-rotating stars is through the indirect measurement of the stellar butterfly diagram: i.e., the change of rotation period determined from light modulation caused by the change in mean latitude of ...
متن کاملdetection of volatile compounds of medicinal plants with some nano-sorbents using modified or new methodologies and investigation of antioxidant activity of their methanolic extracts
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
the differential effects of debate and media analysis as relate to enhancing efl learners critical thinking ability and writing performances
critical thinking ability has an important role in education. accordingly, scholars around the world are searching for new ways for teaching and improving students critical thinking ability. in line with the studies in efl contexts supporting the positive relationship between critical thinking and writing performances, this study investigated the differential effects of halverson’s critical thi...
15 صفحه اولDetection of Y Chromosome Microdeletions and Hormonal Profile Analysis of Infertile Men undergoing Assisted Reproductive Technologies
Objective Y chromosome deletions (YCDs) in azoospermia factor (AZF) region are associated with abnormal spermatogenesis and may lead to azoospermia or severe oligozoospermia. Assisted reproductive technologies (ART) by intracytoplasmic sperm injection (ICSI) and testicular sperm extraction (TESE) are commonly required for infertility management of patients carrying YCDs. The aim of this study w...
