Zooming on the emerging ionized regions of pPNe with ALMA
C. Sánchez Contreras, D. Tafoya, J. P. Fonfría +3
We report on recent results from our successful and pioneering observational program with ALMA to study emerging ultracom pact HII regions of pre-Planetary Nebulae (pPNe) using mm-…
The very compact dust disk in the Red Rectangle
V. Bujarrabal, J. Alcolea, A. Castro-Carrizo +3
We aim to study the dust distribution in the central regions of the Keplerian disk of the Red Rectangle, the prototype of binary post-AGB stars with rotating circumbinary disks, an…
The messy death of a multiple star system and the resulting planetary nebula as observed by JWST
Orsola De Marco, Muhammad Akashi, Stavros Akras +66
Planetary nebulae (PNe), the ejected envelopes of red giant stars, provide us with a history of the last, mass-losing phases of 90 percent of stars initially more massive than the…
A rotating fast bipolar wind and disk system around the B[e]-type star MWC 922
C. Sánchez Contreras, A. Báez-Rubio, J. Alcolea +4
We present interferometric observations with the Atacama Large Millimeter Array (ALMA) of the free-free continuum and recombination line emission at 1 and 3mm of the "Red Square Ne…
Warm CO in evolved stars from the THROES catalogue. II. Herschel/PACS spectroscopy of C-rich envelopes
J. M. da Silva Santos, J. Ramos-Medina, C. Sánchez Contreras +1
This is the second paper of a series making use of Herschel/PACS spectroscopy of evolved stars in the THROES catalogue to study the inner regions of their circumstellar envelopes (…
The maser emitting structure and time variability of the SiS lines J=14-13 and 15-14 in IRC+10216
J. P. Fonfría, M. Fernández-López, J. R. Pardo +8
We present new high angular resolution interferometer observations of the v=0 J=14-13 and 15-14 SiS lines towards IRC+10216, carried out with CARMA and ALMA. The maps, with angular…
