Test of a new method for seismic indices and granulation parameters extraction
EPJ Web of Conferences, 2015 In the framework of the data base project SSI (Stellar Seismic Indicesb), we have developed and tested a new method aiming at optimizing the simultaneous measurement of both the seismic indices characterizing the oscillations (Δν, νmax) and the indices ...

Biodegradable 3D‐Printable and Coatable Antifouling Composites for Marine Applications
Advanced Functional Materials, EarlyView.Marine biofouling damages submerged surfaces and raises greenhouse gas emissions. Biodegradable antifouling biocomposites were developed by hot‐mixing beeswax, Tween 80, and calcium stearate or stearic acid. Adjusting the component ratio enables processing via hot‐pressing, 3D‐printing, or dip‐coating.

Sensitivity of Spectral Lines to Granulation: From the Sun to K-type Stars
The Astrophysical JournalStellar granulation is a source of radial-velocity (RV) jitter of 1 m s ^−1 on Sun-like stars, limiting the detection of Earth analogs. One way to move beyond this limit is to use line-weighting schemes to mitigate granulation-driven RV variability in a ...
