Coronal electron density, temperature and solar spectral irradiance during the solar cycle 23 and 24
J. M Rodríguez Gómez, L. Vieira, A. Dal Lago +1
The plasma parameters such as the electron density and temperature plays a key role in the dynamics of the solar atmosphere. These characteristics are important in solar physics, b…
Preliminary design of the INPE's Solar Vector Magnetograph
L. E. A. Vieira, A. L. Clúa de Gonzalez, A. Dal Lago +23
We describe the preliminary design of a magnetograph and visible-light imager instrument to study the solar dynamo processes through observations of the solar surface magnetic fiel…
Dynamics of the circumstellar gas in the Herbig Ae stars BF Orionis, SV Cephei, WW Vulpeculae and XY Persei
A. Mora, C. Eiroa, A. Natta +22
We present high resolution (lambda / Delta_lambda = 49000) echelle spectra of the intermediate mass, pre-main sequence stars BF Ori, SV Cep, WW Wul and XY Per. The spectra cover th…
Study of the properties and spectral energy distributions of the Herbig AeBe stars HD 34282 and HD 141569
B. Merín, B. Montesinos, C. Eiroa +5
We present a study of the stellar parameters, distances and spectral energy distributions (SEDs) of HD 34282 and HD 141569, two pre-main sequence Herbig AeBe stars. Both objects ha…
A dynamical study of the circumstellar gas in UX Orionis
A. Mora, A. Natta, C. Eiroa +21
We present the results of a high spectral resolution study of the circumstellar (CS) gas around the intermediate mass, pre-main sequence star UX Ori. The results are based on a set…
EXPORT: optical photometry and polarimetry of Vega-type and pre-main sequence stars
R. D. Oudmaijer, J. Palacios, C. Eiroa +1
This paper presents optical UBVRI broadband photo-polarimetry of the EXPORT sample obtained at the 2.5m Nordic Optical Telescope. The database consists of multi-epoch photo-polarim…
