Radiative hydrodynamics simulations of red supergiant stars. III. Spectro-photocentric variability, photometric variability, and consequences on Gaia measurements
A. Chiavassa, E. Pasquato, A. Jorissen +8
Context. It has been shown that convection in red supergiant stars gives rise to large granules causing surface inhomogeneities together with shock waves in the photosphere. The re…
A possible solution to the mass-loss problem in M-type AGB stars
H. Olofsson, S. Ramstedt, S. Sacuto +3
Mass loss is a fundamental, observationally well-established feature of AGB stars but many aspects of this process still remain to be understood. To date, self-consistent dynamical…
Observing and modeling the dynamic atmosphere of the low mass-loss C-star R Sculptoris at high angular resolution
Stéphane Sacuto, Bernhard Aringer, Josef Hron +4
We study the circumstellar environment of the carbon-rich star R Scl using the near- and mid-infrared high spatial resolution observations from the ESO-VLTI instruments VINCI and M…
Angular diameter estimation of interferometric calibrators - Example of lambda Gruis, calibrator for VLTI-AMBER
P. Cruzalebes, A. Jorissen, S. Sacuto +1
Context. Accurate long-baseline interferometric measurements require careful calibration with reference stars. Small calibrators with high angular diameter accuracy ensure the true…
