An image-plane algorithm for JWST's non-redundant aperture mask data
Alexandra Z. Greenbaum, Laurent Pueyo, Anand Sivaramakrishnan +1
The high angular resolution technique of non-redundant masking (NRM) or aperture masking interferometry (AMI) has yielded images of faint protoplanetary companions of nearby stars…
Properties of the CO and HO MOLsphere of the red supergiant Betelgeuse from VLTI/AMBER observations
Miguel Montargès, Pierre Kervella, Guy Perrin +4
Context. Betelgeuse is the closest red supergiant (RSG); therefore, it is well suited for studying the complex processes in its atmosphere that lead to the chemical enrichment of t…
Southern Massive Stars at High Angular Resolution: Observational Campaign and Companion Detection
H. Sana, J. -B. Le Bouquin, S. Lacour +12
Multiplicity is one of the most fundamental observable properties of massive O-type stars and offers a promising way to discriminate between massive star formation theories. Nevert…
An Enigmatic Pointlike Feature within the HD 169142 Transitional Disk
Beth A. Biller, Jared Males, Timothy Rodigas +13
We report the detection of a faint pointlike feature possibly related to ongoing planet-formation in the disk of the transition disk star HD 169142. The pointlike feature has a …
The Science Case for the Planet Formation Imager (PFI)
Stefan Kraus, John Monnier, Tim Harries +16
Among the most fascinating and hotly-debated areas in contemporary astrophysics are the means by which planetary systems are assembled from the large rotating disks of gas and dust…
Planet Formation Imager (PFI): Introduction and Technical Considerations
John D. Monnier, Stefan Kraus, David Buscher +13
Complex non-linear and dynamic processes lie at the heart of the planet formation process. Through numerical simulation and basic observational constraints, the basics of planet fo…
