The onset of the asymmetry in planetary nebulae (PNe) occurs during the short transition between the end of the asymptotic giant branch (AGB) phase and the beginning of the PN phase. Sources in this transition phase are compact and emit intensely in infrared wavelengths, making high spatial resolution observations in the infrared mandatory to investigate the shaping process of PNe. Interferometric VLTI IR observations have revealed compelling evidence of disks at the cores of PNe, but the…

Spectro-astrometry of LkCa 15 with X-Shooter: Searching for emission from LkCa 15b ?

Planet formation is one explanation for the partial clearing of dust observed in the disks of some T Tauri stars. Indeed studies using state-of-the-art high angular resolution techniques have very

Unveiling the near-infrared structure of the massive-young stellar object NGC 3603 IRS 9A with sparse aperture masking and spectroastrometry

Contemporary theory holds that massive stars gather mass during their initial phases via accreting disk-like structures. However, conclusive evidence for disks has remained elusive for the most

SPATIALLY RESOLVING THE KINEMATICS OF THE ≲ 100 &mgr; as ?> QUASAR BROAD-LINE REGION USING SPECTROASTROMETRY

The broad-line region (BLR) of luminous active galactic nuclei (AGNs) is a prominent observational signature of the accretion flow around supermassive black holes, which can be used to measure their

Tachoastrometry: astrometry with radial velocities

Spectra of composite systems (e.g., spectroscopic binaries) contain spatial information that can be retrieved by measuring the radial velocities (i.e., Doppler shifts) of the components in four

Making good use of JWST's coronagraphs: tools and strategies from a user's perspective

TLDR
An end to end observing strategy and data management chain for a few science use cases involving coronagraphs is demonstrated, demonstrating the choice of instrument modes as well as the observing and point-spread function (PSF) subtraction strategies.

VISIR-VLT high-resolution study of the extended emission of four obscured post-AGB candidates

Context. The onset of the asymmetry of planetary nebulae (PNe) is expected to occur during the late asymptotic giant branch (AGB) and early post-AGB phases of low- and intermediate-mass stars. Among

Spectro-astrometry: The Method, its Limitations, and Applications

Intermediate resolution spectroscopic observations provide a window into the immediate environment of young stars. In particular, such studies have yielded a lot of new information regarding outflow

A mid-infrared imaging catalogue of post-asymptotic giant branch stars

Post-asymptotic giant branch (post-AGB) stars are key objects for the study of the dramatic morphological changes of low- to intermediate-mass stars on their evolution from the AGB towards the
