Sensitivity of spectral lines to granulation: The Sun
K. Sowmya, A. I. Shapiro, V. Vasilyev +3
The intrinsic variability of stars, due to acoustic oscillations, surface granulation, and magnetic activity, introduces radial velocity (RV) jitter in spectral lines, obscuring tr…
Superflares on solar-like stars: A new method for identifying the true flare sources in photometric surveys
Valeriy Vasilyev, Timo Reinhold, Alexander I. Shapiro +5
Over the past years, thousands of stellar flares have been detected by harvesting data from large photometric surveys. These detections, however, do not account for potential sourc…
Two-dimensional non-LTE \ion{O}{I} 777\,nm line formation in radiation hydrodynamics simulations of Cepheid atmospheres
V. Vasilyev, A. M. Amarsi, H. -G. Ludwig +1
Oxygen abundance measurements are important for understanding stellar structure and evolution. Measured in Cepheids, they further provide clues on the metallicity gradient and chem…
Spectroscopic properties of a two-dimensional time-dependent Cepheid model II. Determination of stellar parameters and abundances
V. Vasilyev, H. -G. Ludwig, B. Freytag +2
Standard spectroscopic analyses of variable stars are based on hydrostatic one-dimensional model atmospheres. This quasi-static approach has theoretically not been validated. We ai…
First results of the search of neutrinoless double beta decay with the NEMO 3 detector
R. Arnold
The NEMO 3 detector, which has been operating in the Frejus underground laboratory since February 2003, is devoted to the search for neutrinoless double beta decay (bb0nu). Half-li…
Study of 2b-decay of Mo-100 and Se-82 using the NEMO3 detector
the NEMO Collaboration, R. Arnold
After analysis of 5797 h of data from the detector NEMO3, new limits on neutrinoless double beta decay of Mo-100 (T_{1/2} > 3.1 10^{23} y, 90% CL) and Se-82 (T_{1/2} > 1.4 10^{23}…
Possible background reductions in double beta decay experiments
R. Arnold, C. Augier, J. Baker +38
The background induced by radioactive impurities of and in the source of the double beta experiment NEMO-3 has been investigated. New methods of data…
