A technique to study several regions of plasma produced by laser ablation in a single laser pulse is presented. The technique is based on a field spectrograph, an instrument where the image of the plasma is captured with a number of fibers in a user

Solving the statistical equilibrium equations we find line intensity ratios of C III, N III, O III, Si III, and Al III in the visible and ultraviolet range, that are sensitive to electron density and/or temperature in the regime commonly found in pul

"Open slit high dispersion spectroscopic observations of the inner region of planetary nebula (PN) IC 2165 indicate that the object has a relatively uniform and high electron temperature, with its density being much larger close to the PN nucleus. Ab

"Optical spectroscopy of the entire planetary nebula M 1-9, reveals pronounced density variations, a temperature distribution where Te(N+) is larger than Te(O+2) and abundances indicating that it is a halo planetary nebulae, an association supported

"Weather observations carried out between October 2004 and July 2008 at the Mexican Observatorio Astronómico Nacional (OAN) are analyzed. Humidity in April, May and June was less than 55% nearly 90% of the time. Wind speed was larger at nightime and

"In ionized regions with temperature gradients and uctuations, the ratio of the ion abundance obtained from a recombination line to that found from a colli- sionally excited line (CEL), or ADF, is smaller than observed (ADF ? 2). Larger ADFs are foun

"Good to excellent photoionization models based on the Cloudy code were obtained for 13 out of 19 spectra of planetary nebulae. The two most important assumptions are that the photoionizing continuum is a Rauch model star, with gravity set by the con
