European VLBI Network observations of 6.7-GHz methanol masers in a candidate circumstellar disc
Lisa Harvey-Smith, Rebeca Soria-Ruiz
The first high-resolution (5 mas) VLBI observations of 6.7-GHz methanol masers in DR21(OH)N, a candidate circumstellar disc around a very young massive star, are presented. Previou…
First images of 6.7-GHz methanol masers in DR21(OH) and DR21(OH)N
L. Harvey-Smith, R. Soria-Ruiz, A. Duarte-Cabral +1
The first images of 6.7-GHz methanol masers in the massive star-forming regions DR21(OH) and DR21(OH)N are presented. By measuring the shapes, radial velocities and polarization pr…
First VLBI mapping of a rare SiO isotopic substitution
R. Soria-Ruiz, F. Colomer, J. Alcolea +3
We report the first VLBI map of the 7 mm v=0 J=1-0 maser line of the 29-SiO isotopic substitution in the long period variable star IRC+10011. We have found that this maser emission…
High resolution observations of SiO masers: comparing the spatial distribution at 43 and 86 GHz
R. Soria-Ruiz, J. Alcolea, F. Colomer +4
We present sub-milliarcsecond observations of SiO masers in the late-type stars IRC +10011 and Chi Cyg. We have used the NRAO Very Long Baseline Array (VLBA) to map the 43 GHz (v=1…
Multi-transition VLBA observations of circumstellar SiO masers
R. Soria-Ruiz, F. Colomer, J. Alcolea +5
On this paper, we present simultaneous VLBA observations of the J=1-0 and J=2-1 rotational lines in the v=1 and v=2 vibrationally excited states of SiO (at 7 and 3 mm wavelengths).…
The Relative Spatial Distribution of SiO Masers in AGB Stars at 43 and 86 GHz
J. -F. Desmurs, R. Soria-Ruiz, F. Colomer +6
We present the first VLBI images of SiO masers in the circumstellar envelope of an S-type star obtained with the newly developed capabilities of the Very Long Baseline Array (VLBA)…
