OH+ in Diffuse Molecular Clouds

A. J. Porras, S. R. Federman, D. E. Welty +1

Near ultraviolet observations of OH+ and OH in diffuse molecular clouds reveal a preference for different environments. The dominant absorption feature in OH+ arises from a main co…

Towards a better understanding of the distance scale from RR Lyrae variable stars: A case study for the inner halo globular cluster NGC 6723

Jae-Woo Lee, Mercedes Lopez-Morales, Kyeong-Soo Hong +3

We present BV photometry for 54 variables in the metal-rich inner halo globular cluster NGC6723. With the discovery of new RR Lyrae variables (RRLs), we obtain <P_ab> = 0.541 +/- 0…

Large scale IRAM 30m CO-observations in the giant molecular cloud complex W43

P. Carlhoff, Q. Nguyen Luong, P. Schilke +11

We aim to give a full description of the distribution and location of dense molecular clouds in the giant molecular cloud complex W43. It has previously been identified as one of t…

Gravitational Infall onto Molecular Filaments II. Externally Pressurized Cylinders

Fabian Heitsch

In an extension of Fischera & Martin (2012a) and Heitsch (2013), two aspects of the evolution of externally pressurized, hydrostatic filaments are discussed. (a) The free-fall accr…

Low-velocity shocks traced by extended SiO emission along the W43 ridges: witnessing the formation of young massive clusters

Q. Nguyen Luong, F. Motte, P. Carlhoff +19

The formation of high-mass stars is tightly linked to that of their parental clouds. We here focus on the high-density parts of W43, a molecular cloud undergoing an efficient event…

Gravitational Infall onto Molecular Filaments

Fabian Heitsch

Two aspects of filamentary molecular cloud evolution are addressed: (1) Exploring analytically the role of the environment for the evolution of filaments demonstrates that consider…

The Effects of Inhomogeneities within Colliding Flows on the Formation and Evolution of Molecular Clouds

Jonathan Carroll-Nellenback, Adam Frank, Fabian Heitsch

Observational evidence from local star-forming regions mandates that star formation occurs shortly after, or even during, molecular cloud formation. Models of the formation of mole…
