ATOMIUM: Probing the inner wind of evolved O-rich stars with new, highly excited HO and OH lines

A. Baudry, K. T. Wong, S. Etoka +17

Water and the hydroxyl radical are major constituents of the envelope of O-rich late-type stars. Transitions involving energy levels that are highly excited have been observed in b…

The VLT/SPHERE view of the ATOMIUM cool evolved star sample. I. Overview: Sample characterization through polarization analysis

M. Montargès, E. Cannon, A. de Koter +32

Aims. Through the ATOMIUM project, based on an ALMA large program, we aim to present a consistent view of a sample of 17 nearby cool evolved stars (Aymptotic Giant Branch and red s…

ATOMIUM: ALMA tracing the origins of molecules in dust forming oxygen rich M-type stars: Motivation, sample, calibration, and initial results

C. A. Gottlieb, L. Decin, A. M. S. Richards +33

This overview paper presents ATOMIUM, a Large Programme in Cycle 6 with the Atacama Large Millimeter-submillimeter Array (ALMA). The goal of ATOMIUM is to understand the dynamics a…

Rotational spectra of vibrationally excited AlO and TiO in oxygen rich stars

T. Danilovich, C. A. Gottlieb, L. Decin +6

Rotational transitions in vibrationally excited AlO and TiO -- two possible precursors of dust -- were observed in the 300 GHz range (1 mm wavelength) towards the oxygen rich AGB s…

(Sub)stellar companions shape the winds of evolved stars

L. Decin, M. Montargès, A. M. S. Richards +32

Binary interactions dominate the evolution of massive stars, but their role is less clear for low- and intermediate-mass stars. The evolution of a spherical wind from an asymptotic…

An ALMA view of SO and SO around oxygen-rich AGB stars

T. Danilovich, A. M. S. Richards, L. Decin +2

We present and analyse SO and SO, recently observed with high angular resolution and sensitivity in a spectral line survey with ALMA, for two oxygen-rich AGB stars: the low mas…

The growth of carbon chains in IRC+10216 mapped with ALMA

M. Agundez, J. Cernicharo, G. Quintana-Lacaci +9

Linear carbon chains are common in various types of astronomical molecular sources. Possible formation mechanisms involve both bottom-up and top-down routes. We have carried out a…

An observational study of dust nucleation in Mira ( Ceti): II. Titanium oxides are negligible for nucleation at high temperatures

T. Kamiński, H. S. P. Müller, M. R. Schmidt +7

The formation of silicate dust in oxygen-rich envelopes of evolved stars is thought to be initiated by formation of seed particles that can withstand the high temperatures close to…

An observational study of dust nucleation in Mira ( Ceti): I. Variable features of AlO and other Al-bearing species

T. Kamiński, K. T. Wong, M. R. Schmidt +8

Context: Dust is efficiently produced by cool giant stars, but the condensation of inorganic dust is poorly understood. Aims: Identify and characterize aluminum bearing species in…

Vibrationally Excited CH

Andrew L. Cooksy, C. A. Gottlieb, T. C. Killian +4

Rotational spectra in four new excited vibrational levels of the linear carbon chain radical CH radical were observed in the millimeter band between 69 and 364 GHz in a low pre…

Dust-forming molecules in VY Canis Majoris (and Betelgeuse)

T. Kaminski, C. A. Gottlieb, M. R. Schmidt +7

The formation of inorganic dust in circumstellar environments of evolved stars is poorly understood. Spectra of molecules thought to be most important for the nucleation, i.e. AlO,…

An Interferometric Spectral-line Survey of IRC+10216 in the 345 GHz Band

Nimesh A. Patel, Ken H. Young, Carl A. Gottlieb +10

We report a spectral-line survey of the extreme carbon star IRC+10216 carried out between 293.9 and 354.8 GHz with the Submillimeter Array. A total of 442 lines were detected, more…
