The Optical Spectroscopic Evolution of V1974 Cygni (Nova Cygni 1992)
A. Moro-Martin, P. M. Garnavich, A. Noriega-Crespo
Optical observations of nova V1974 Cygni (Cygni 1992), spanning a 4 year period, have been used to study its spectroscopic evolution. The data cover a wavelength range from $\sim 3…
A Shock-Induced PDR in the HH 80/81 Flow. Far Infrared Spectroscopy
Sergio Molinari, Alberto Noriega-Crespo, Luigi Spinoglio
The two spectrometers on board the Infrared Space Observatory were used to observe the Herbig-Haro objects HH 80, 81 and 80N, as well as their candidate exciting source IRAS 18162-…
Windows through the Dusty Disks Surrounding the Youngest Low Mass Protostellar Objects
J. Cernicharo, A. Noriega-Crespo, D. Cesarsky +5
The formation and evolution of young low mass stars are characterized by important processes of mass loss and accretion ocurring in the innermost regions of their placentary circum…
Optical and Near Infrared Study of the Cepheus E outflow, a very low excitation object
S. Ayala, A. Noriega-Crespo, P. M. Garnavich +4
We present images and spectra of the Cepheus E (Cep E) region at both optical and infrared wavelengths. Only the brightest region of the southern lobe of the Cep E outflow reveals…
ISO Spectroscopy of the HH 7-11 Flow and its red-shifted Counterpart
S. Molinari, A. Noriega-Crespo, C. Ceccarelli +7
We have used the two spectrometers on the Infrared Space Observatory to observe the HH 7-11 flow, its red-shifted counterpart, and the candidate exciting source SVS 13, in the star…
