A measurement of the I = I solar rotational splitting
A precise measurement of the l = 1 rotational splitting has been derived from the 1991 IRIS data and it leads to a moderate rotation rate in the solar core.
A meta-analysis of the magnetic line broadening in the solar atmosphere
A multiline Bayesian analysis of the Zeeman broadening in the solar atmosphere is presented. A hierarchical probabilistic model, based on the simple but...
A metamaterial with applications in broad band antennas used in radio astronomy and satellite communications
Electromagnetic metamaterials at microwave frequencies are well established in industry and research. Recent work has shown how a specific kind of metallic...
A meteorological and photometric study of the Oukaimeden site. Comparison with the Observatorio del Roque de los Muchachos using Carlsberg Automatic Meridian Circle data
In this paper, we present meteorological and photometric studies of the Oukaimeden astronomical site in Morocco. The meteorological measurements were obtained...
A Methane, Isolated, Planetary-Mass Object in Orion
We report on the discovery of a free-floating methane dwarf toward the direction of the young star cluster σ Ori. Based on the object's far-red, optical, and...
A method to deconvolve stellar profiles. The non-rotating line utilizing Gaussian sum approximation
Context. Currently, one of the standard procedures used to determine stellar and wind parameters of massive stars involves to comparing the observed spectral...
A method to detect p-mode oscillations in solar-like star signals
A good example of finding a signal buried in noise, a common problem in Astrophysics, is the search for stellar oscillations in the acoustic power spectrum of...
A method to measure the mirror reflectivity of a prime focus telescope
We have developed a method to measure the mirror reflectivity of telescopes. While it is relatively easy to measure the local reflectivity of the mirror...
A microwave blackbody target for cosmic microwave background spectral measurements in the 10–20 GHz range
The Tenerife Microwave Spectrometer (TMS) is a ground-based radio-spectrometer that will take absolute measurements of the sky between 10–20 GHz. To ensure the...
