HST/NICMOS observations of the GLIMPSE9 stellar cluster
Maria Messineo, Donald F. Figer, Ben Davies +4
We present HST/NICMOS photometry, and low-resolution K-band spectra of the GLIMPSE9 stellar cluster. The newly obtained color-magnitude diagram shows a cluster sequence with H-Ks =…
The circumstellar disk, envelope, and bi-polar outflow of the Massive Young Stellar Object W33A
Ben Davies, Stuart L. Lumsden, Melvin G. Hoare +2
The Young Stellar Object (YSO) W33A is one of the best known examples of a massive star still in the process of forming. Here we present Gemini North ALTAIR/NIFS laser-guide star a…
The progenitor mass of the magnetar SGR1900+14
Ben Davies, Don F. Figer, Rolf-Peter Kudritzki +3
Magnetars are young neutron stars with extreme magnetic fields (B > 10^{14}-10^{15}G). How these fields relate to the properties of their progenitor stars is not yet clearly establ…
On the presence and absence of disks around O-type stars
Jorick S. Vink, B. Davies, T. J. Harries +2
(abridged) As the favoured progenitors of long-duration gamma-ray bursts, massive stars may represent our best signposts of individual objects in the early Universe, but special co…
A Near-Infrared Study of the Stellar Cluster: [DBS2003] 45
Qingfeng Zhu, Ben Davies, Donald F. Figer +1
We present a multi-wavelength photometric and spectroscopic study of a newly discovered candidate cluster [DBS2003] 45. Our H, Ks photometry confirms that [DBS2003] 45 is a cluster…
Near-infrared spectra of Galactic stellar clusters detected on Spitzer/GLIMPSE images
Maria Messineo, Ben Davies, Valentin D. Ivanov +5
We present near-infrared spectroscopic observations of massive stars in three stellar clusters located in the direction of the inner Galaxy. One of them, the Quartet, is a new disc…
