A new radial system of dark globules in Monoceros
C. Carrasco-González, R. López, A. Gyulbudaghian +2
Aims. We analyze the LBN 978 HII region in order to study the HII/molecular cloud interaction. Methods. We used the IAC-80 telescope to image the region with narrow-band filters an…
Astrometric Light-Travel Time signature of sources in nonlinear motion
Guillem Anglada, Jordi Torra
Context:Very precise planned space astrometric missions and recent improvements on imaging capabilities require a detailed review of the assumptions of classical astrometric modeli…
Relativistic effects on the imaging by a rotating optical system
G. Anglada-Escude, S. Klioner, M. Soffel +1
Context. High accuracy astrometric instruments like Gaia aiming at an accuracy of 1 microarcsecond cannot be considered as point-like observers in the framework of relativistic mod…
Spectral index of the H2O-maser emitting planetary nebula IRAS 17347-3139
J. F. Gomez, I. de Gregorio-Monsalvo, J. E. J. Lovell +5
We present radio continuum observations of the planetary nebula (PN) IRAS 17347-3139 (one of the only two known to harbour water maser emission), made to derive its spectral index…
High-Resolution Molecular Line Observations of the Environment of the Class 0 Source B1-IRS
I. de Gregorio-Monsalvo, C. J. Chandler, J. F. Gomez +3
In this work we present VLA observations of the NH3, CCS, and H2O maser emission at 1 cm from the star forming region B1-IRS (IRAS 03301+3057) with ~ 5" (=1750 AU) of angular resol…
