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…
The circumstellar disc around the Herbig AeBe star HD169142
W. R. F. Dent, J. M. Torrelles, M. Osorio +2
We present 7 mm and 3.5 cm wavelength continuum observations toward the Herbig AeBe star HD169142 performed with the Very Large Array (VLA) with an angular resolution of ~1". We fi…
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…
A disk of dust and molecular gas around a high-mass protostar
Nimesh A. Patel, Salvador Curiel, T. K. Sridharan +7
The processes leading to the birth of low-mass stars such as our Sun have been well studied, but the formation of high-mass (> 8 x Sun's mass) stars has heretofore remained poorly…
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…
