High-resolution observations of edge-on proto-planetary disks in emission from molecular species sampling different critical densities and formation pathways offer the opportunity…
Design of the Life Signature Detection Polarimeter LSDpol
Christoph U. Keller, Frans Snik, C. H. Lucas Patty +11
Many biologically produced chiral molecules such as amino acids and sugars show a preference for left or right handedness (homochirality). Light reflected by biological materials s…
ALMA chemical survey of disk-outflow sources in Taurus (ALMA-DOT) V: Sample, overview, and demography of disk molecular emission
Antonio Garufi, Linda Podio, Claudio Codella +9
We present an overview of the ALMA chemical survey of disk-outflow sources in Taurus (ALMA-DOT), a campaign devoted to the characterization of the molecular emission from partly em…
DiskFM: A Forward Modeling Tool for Disk Analysis with Coronagraphic Instruments
Johan Mazoyer, Pauline Arriaga, Justin Hom +6
Because of bright starlight leakage in coronagraphic raw images, faint astrophysical objects such as exoplanets can only be detected using powerful point spread function (PSF) subt…
VLTI images of circumbinary disks around evolved stars
Jacques Kluska, Rik Claes, Akke Corporaal +13
The new generation of VLTI instruments (GRAVITY, MATISSE) aims to produce routinely interferometric images to uncover the morphological complexity of different objects at high angu…
Operational forecast of the PSF figures of merit
A. Turchi, G. Agapito, E. Masciadri +6
The optimization and scheduling of scientific observations done with instrumentation supported by adaptive optics could greatly benefit from the forecast of PSF figures of merit (F…
H mass-velocity relationship from 3D numerical simulations of jet-driven molecular outflows
Adriano Cerqueira, Bertrand Lefloch, Alejandro Esquivel +4
Previous numerical studies have shown that in protostellar outflows, the mass-velocity distribution can be well described by a broken power law . On the oth…
Gaia Early Data Release 3 -- Catalogue validation
C. Fabricius, X. Luri, F. Arenou +33
The third Gaia data release is published in two stages. The early part, Gaia EDR3, gives very precise astrometric and photometric properties for nearly two billion sources together…
The asymmetric inner disk of the Herbig Ae star HD 163296 in the eyes of VLTI/MATISSE: evidence for a vortex?
J. Varga, M. Hogerheijde, R. van Boekel +133
Context. The inner few au region of planet-forming disks is a complex environment. High angular resolution observations have a key role in understanding the disk structure and the…
Investigating three Sirius-like systems with SPHERE
R. Gratton, V. D'Orazi, T. A. Pacheco +61
Sirius-like systems are wide binaries composed of a white dwarf (WD) and a companion of a spectral type earlier than M0. The WD progenitor evolves in isolation, but its wind during…
A highly non-Keplerian protoplanetary disc: Spiral structure in the gas disc of CQ Tau
Lisa Wölfer, Stefano Facchini, Nicolas T. Kurtovic +9
In the past years, high angular resolution observations have revealed that circumstellar discs appear in a variety of shapes with diverse substructures being ubiquitous. This has g…
