High Spectral Resolution Observations of the Massive Stars in the Galactic Center
Angelle Tanner, Donald F. Figer, Paco Najarro +10
We present high-resolution near-infrared spectra, obtained with the NIRSPEC spectrograph on the W. M. Keck II Telescope, of a collection of hot, massive stars within the central 25…
Probing Dark Energy via Weak Gravitational Lensing with the SuperNova Acceleration Probe (SNAP)
SNAP Collaboration
SNAP is a candidate for the Joint Dark Energy Mission (JDEM) that seeks to place constraints on the dark energy using two distinct methods. The first, Type Ia SN, is discussed in a…
Theoretical Isochrones with Extinction in the K Band
Sungsoo S. Kim, Donald F. Figer, Myung Gyoon Lee +1
We calculate theoretical isochrones in a consistent way for five filters (K, K', Ks, F205W, and F222M) in the atmospheric window between 1.9 and 2.5 micron using the Padova stellar…
An upper limit to the masses of stars
Donald F. Figer
There is no accepted upper mass limit for stars. Such a basic quantity escapes both theory, because of incomplete understanding of star formation, and observation, because of incom…
Massive Stars in the SGR 1806-20 Cluster
Donald F. Figer, Francisco Najarro, T. R. Geballe +2
We report the discovery of additional hot and massive stars in the cluster surrounding the soft gamma repeater SGR 1806-20, based upon UKIRT and Keck near-infrared spectroscopy. Of…
