Cepheid distances from the SpectroPhoto-Interferometry of Pulsating Stars (SPIPS) - Application to the prototypes delta Cep and eta Aql
Antoine Merand, Pierre Kervella, Joanne Breitfelder +8
The parallax of pulsation, and its implementations such as the Baade-Wesselink method and the infrared surface bright- ness technique, is an elegant method to determine distances o…
VLTI status update: a decade of operations and beyond
Antoine Merand, Roberto Abuter, Emmanuel Aller-Carpentier +44
We present the latest update of the European Southern Observatory's Very Large Telescope interferometer (VLTI). The operations of VLTI have greatly improved in the past years: redu…
Mass of Cepheid V350 Sgr Incorporating Interferometry and the Companion Mass
Nancy Remage Evans, Alexandre Gallenne, Pierre Kervella +8
The system V350 Sgr has a classical Cepheid for the primary. Interferometry is presented for the system and the full orbit is determined. The mass of the companion has been determi…
The spin-orbit alignment of the Fomalhaut planetary system probed by optical long baseline interferometry
Jean-Baptiste Le Bouquin, Olivier Absil, Myriam Benisty +3
We discuss the spin-orbit orientation of the Fomalhaut planetary system composed of a central A4V star, a debris disk, and a recently discovered planetary companion. We use spectra…
X-shooter, NACO, and AMBER observations of the LBV Pistol Star \footnote{Based on ESO runs 85.D-0182A, 085.D-0625AC}
Christophe Martayan, Ronny Blomme, Jean-Baptiste Le Bouquin +15
We present multi-instruments and multi-wavelengths observations of the famous LBV star Pistol Star. These observations are part of a larger program about early O stars at different…
Pre-maximum spectro-imaging of the Mira star T Lep with AMBER/VLTI
Jean-Baptiste Le Bouquin, Sylvestre Lacour, Stephanie Renard +3
Diffuse envelopes around Mira variables are among the most important sources influencing the chemical evolution of galaxies. However they represent an observational challenge becau…
