NLTE Stellar Population Synthesis of Globular Clusters using Synthetic Integrated Light Spectra I: Constructing the IL Spectra
Mitchell E. Young, C. Ian Short
We present an investigation of the globular cluster population synthesis method of McWilliam & Bernstein (2008), focusing on the impact of NLTE modeling effects and CMD discretizat…
V473 Lyr, a modulated, period-doubled Cepheid, and U TrA, a double-mode Cepheid observed by MOST
L. Molnár, A. Derekas, R. Szabó +36
Space-based photometric measurements first revealed low-amplitude irregularities in the pulsations of Cepheid stars, but their origins and how commonly they occur remain uncertain.…
The VIMOS Public Extragalactic Redshift Survey (VIPERS): PCA-based automatic cleaning and reconstruction of survey spectra
A. Marchetti, B. Garilli, B. R. Granett +34
Identifying spurious reduction artefacts in galaxy spectra is a challenge for large surveys. We present an algorithm for identifying and repairing residual spurious features in sky…
Measurement of excitation spectra in the C reaction near the emission threshold
Y. K. Tanaka, K. Itahashi, H. Fujioka +51
Excitation spectra of C were measured in the C reaction near the emission threshold. A proton beam extracted from the synchrotron SIS-18 at GSI with an in…
Measurement of the pi^0 -> e^+e^-gamma Dalitz decay at the Mainz Microtron
P. Adlarson, F. Afzal, P. Aguar-Bartolomé +94
The Dalitz decay pi^0 -> e^+e^-gamma has been measured in the gamma p -> pi^0 p reaction with the A2 tagged-photon facility at the Mainz Microtron, MAMI. The value obtained for the…
No Conclusive Evidence for Transits of Proxima b in MOST photometry
David M. Kipping, Chris Cameron, Joel D. Hartman +21
The analysis of Proxima Centauri's radial velocities recently led Anglada-Escudé et al. (2016) to claim the presence of a low mass planet orbiting the Sun's nearest star once every…
