CCD images and near-IR observations of the nebular objects GGD 30 and GGD 31 are presented. The data have been used to study the morphology and physical nature of the nebulosities. GGD 30 is a reflection nebula illuminated by a low mass PMS star[...]texto impreso

Martínez Arnáiz, R. ; Maldonado, J. ; Montes Gutiérrez, David ; Eiroa, C. ; Montesinos, B. | EDP Sciencies | 2010-09Context. Chromospheric activity produces both photometric and spectroscopic variations that can be mistaken as planets. Large spots crossing the stellar disc can produce planet-like periodic variations in the light curve of a star. These spots c[...]texto impreso
We have obtained new deep I, H(alpha) and [SII] CCD images of several fields in the star formation region NGC 7129. The data are presented in the form of grey-level pictures or isocontour plots. A large and complex nebulosity has been discovered[...]texto impreso
Martínez Arnáiz, R. M. ; Maldonado, J. ; Montes Gutiérrez, David ; Eiroa, C. ; Montesinos, B. ; Ribas, I. ; Solano, E. | American Institute of Physics | 2009We present the most recent results of our ongoing long-term high resolution spectroscopic study of nearby (d ? 25 pc) FGK stars which aim is to characterize the local properties of the Galaxy, in particular the star-formation history. A through [...]texto impreso
CCD images and spectra of high spectral resolution of GGD 34 are analyzed. The object is a jet consisting of three major condensations separated 0.08 pc one of each other and aligned over 0.17pc in the east-west direction. The three condensation[...]texto impreso
We present CCD images and long-slit spectra of the nebulous object GGD 33 and of the T Tauri star V 350 Cep in the star formation region NGC 7129. The data suggest that GGD 33a is a T Tauri star and likely the illuminating source of the whole GG[...]texto impreso
We present CCD images of the central part of the star forming region NGC 7129 as well as spectra of moderate spectral and high spatial resolution of some nebular objects and stars. The images show many reflection filaments which seem to trace th[...]texto impreso

Maldonado, J. ; Martínez Arnáiz, R. M. ; Eiroa, C. ; Montes Gutiérrez, David ; Montesinos, B. | EDP Sciencies | 2010-10Context. Nearby late-type stars are excellent targets for seeking young objects in stellar associations and moving groups. The origin of these structures is still misunderstood, and lists of moving group members often change with time and also f[...]
