The FU Ori outburst of PR Ori B
Carlos Contreras Pena, Zsofia Nagy, Gregory Herczeg +42
We report the discovery of a nearby FU Ori-type outburst (FUor), PR Ori B, in the L1641 cluster of the Orion star-forming region. The high-amplitude variability was first identifie…
Evidence for an accretion bridge in the DX Cha circumbinary system from VLTI/MATISSE observations
Tímea Juhász, József Varga, Péter Ábrahám +20
DX Cha (HD 104237) is a spectroscopic binary consisting of a Herbig A7.5Ve-A8Ve primary star and a K3-type companion. Here we report on new micrometer interferometric observ…
From an amateur PN candidate to the Rosetta Stone of SN Iax research
Andreas Ritter, Quentin A. Parker, Foteini Lykou +3
On August 25th 2013 Dana Patchick from the "Deep Sky Hunters" (DSH) amateur astronomer group discovered a diffuse nebulosity in the Wide-field Infrared Survey Explorer (WISE) mid-I…
The messy death of a multiple star system and the resulting planetary nebula as observed by JWST
Orsola De Marco, Muhammad Akashi, Stavros Akras +66
Planetary nebulae (PNe), the ejected envelopes of red giant stars, provide us with a history of the last, mass-losing phases of 90 percent of stars initially more massive than the…
A new study on a type Iax stellar remnant and its probable association with SN 1181
Foteini Lykou, Quentin A. Parker, Andreas Ritter +4
We report observations and modeling of the stellar remnant and presumed double-degenerate merger of Type~Iax supernova Pa30, which is the probable remnant of SN~1181~AD. It is the…
The remnant and origin of the historical supernova 1181AD
Andreas Ritter, Quentin Parker, Foteini Lykou +3
The guest star of AD 1181 is the only historical supernova of the last millennium that is without a definite counterpart. The previously proposed association with supernova remnant…
The infrared view of dust and molecules around V4334 Sgr (Sakurai's Object): a 20-year retrospective
A. Evans, R. D. Gehrz, C. E. Woodward +16
We present an analysis of the evolution of circumstellar dust and molecules in the environment of the very late thermal pulse object V4334 Sgr (Sakurai's Object) over a -ye…
The Central Star of Planetary Nebula PHR 1315-6555 and its host Galactic Open Cluster AL 1
V. Fragkou, Q. A. Parker, A. A. Zijlstra +2
PHR 1315-6555 is a rare case of a Galactic Planetary Nebula that is a proven member of the Open Cluster AL 1. This allows its distance to be defined with precision and thus the acc…
Central Stars of Planetary Nebulae in Galactic Open Clusters: Providing additional data for the White Dwarf Initial-to-Final-Mass Relation
Vasiliki Fragkou, Quentin A. Parker, Albert Zijlstra +2
Accurate (<10%) distances of Galactic star clusters allow precise estimation of the physical parameters of any physically associated Planetary Nebula (PN) and also that of its cent…
The curious case of II Lup: a complex morphology revealed with SAM/NACO and ALMA
Foteini Lykou, Albert A. Zijlstra, Jacques Kluska +5
We present the first-ever images of the circumstellar environment of the carbon-rich AGB star II Lup in the infrared and sub-mm wavelengths, and the discovery of the envelope's non…
A close halo of large transparent grains around extreme red giant stars
Barnaby R. M. Norris, Peter G. Tuthill, Michael J. Ireland +6
Intermediate-mass stars end their lives by ejecting the bulk of their envelope via a slow dense wind back into the interstellar medium, to form the next generation of stars and pla…
A disk inside the bipolar planetary nebula M2-9
Foteini Lykou, Olivier Chesneau, Albert A. Zijlstra +4
Bipolarity in proto-planetary and planetary nebulae is associated with events occurring in or around their cores. Past infrared observations have revealed the presence of dusty str…
A disc in the heart of the Ant nebula
Foteini Lykou, Olivier Chesneau, Eric Lagadec +1
We present the discovery of a silicate disc at the centre of the planetary nebula Mz3 (the Ant). The nebula was observed with MIDI on the Very Large Telescope Interferometer (VLTI)…
A silicate disk in the heart of the Ant
Olivier Chesneau, Foteini Lykou, Bruce Balick +6
We aim at getting high spatial resolution information on the dusty core of bipolar planetary nebulae to directly constrain the shaping process. Methods: We present observations of…
