Everything that glitters is not gold: V1315 Cas is not a dormant black hole
J. Zak, D. Jones, H. M. J. Boffin +11
The quest for quiet or dormant black holes has been ongoing since several decades. Ellipsoidal variables possibly indicate the existence of a very high-mass invisible companion and…
PM 1-322: new variable planetary nebula
E. Paunzen, K. Bernhard, J. Budaj +4
Spectra of planetary nebulae (PNe) are characterised by strong forbidden emission lines and often also by an infrared (IR) excess. A few PNe show dust obscuration events and/or har…
Planetary nebulae hosting accreting white dwarfs: A possible solution for the mysterious cut-off of Planetary Nebula Luminosity Function?
D. Souropanis, A. Chiotellis, P. Boumis +2
Many binary companions to the central stars of planetary nebulae (PNe) are found to be inflated, perhaps indicating that accretion onto the central star might occur during the PN p…

S. Akras, H. Monteiro, J. R. Walsh +11
Integral field spectroscopy (IFS) provides a unique capability to spectroscopically study extended sources over a 2D field of view, but it also requires new techniques and tools. I…
The ionised and molecular mass of post-common-envelope planetary nebulae. The missing mass problem
M. Santander-García, D. Jones, J. Alcolea +2
Most planetary nebulae (PNe) show beautiful, axisymmetric morphologies despite their progenitor stars being essentially spherical. Close binarity is widely invoked to help eject an…
Towards a more complete sample of binary central stars of planetary nebulae with Gaia
N. Chornay, N. A. Walton, D. Jones +3
Context: Many if not most planetary nebulae (PNe) are now thought to be the outcome of binary evolutionary scenarios. However only a few percent of PNe in the Milky Way are known t…

S. A. Rappaport, D. W. Kurtz, G. Handler +13
We report the discovery of the third tidally tilted pulsator, TIC 63328020. Observations with the TESS satellite reveal binary eclipses with an orbital period of 1.1057 d, and …
Nebulosities of the Symbiotic Binary R Aquarii -- A Short Review
T. Liimets, R. M. L. Corradi, D. Jones +3
In this proceeding, we present a short review of the fascinating nebulosities of symbiotic binary R Aquarii. The R Aquarii system, comprising the central binary and surrounding neb…
Tidally Trapped Pulsations in a close binary star system discovered by TESS
G. Handler, D. W. Kurtz, S. A. Rappaport +12
It has long been suspected that tidal forces in close binary stars could modify the orientation of the pulsation axis of the constituent stars. Such stars have been searched for, b…
AT 2019abn: multi-wavelength observations over the first 200 days
S. C. Williams, D. Jones, P. Pessev +8
AT 2019abn was discovered in the nearby M51 galaxy by the Zwicky Transient Facility at more than two magnitudes and around three weeks prior to its optical peak. We aim to conduct…
Latest advances in the abundance discrepancy problem in photoionized nebulae
J. García-Rojas, R. Wesson, H. M. J. Boffin +4
In this paper, we will focus on the advances made in the last few years regarding the abundance discrepancy problem in ionized nebulae. We will show the importance of collecting de…
Spectral analysis of the barium central star of the planetary nebula Hen 2-39
L. Löbling, H. M. J. Boffin, D. Jones
Barium stars are peculiar red giants characterized by an overabundance of s-process elements along with an enrichment in carbon. These stars are discovered in binaries with white d…
New insights into the outflows from R Aquarii
T. Liimets, R. L. M. Corradi, D. Jones +8
R Aquarii is a symbiotic binary surrounded by a large and complex nebula with a prominent curved jet. It is one of the closest known symbiotic systems, and therefore offers a uniqu…
A new look inside Planetary Nebula LoTr 5: A long-period binary with hints of a possible third component
A. Aller, J. Lillo-Box, M. Vučković +5
LoTr 5 is a planetary nebula with an unusual long-period binary central star. As far as we know, the pair consists of a rapidly rotating G-type star and a hot star, which is respon…
The double-degenerate, super-Chandrasekhar nucleus of the planetary nebula Henize 2-428
M. Santander-García, P. Rodríguez-Gil, R. L. M. Corradi +5
The planetary nebula (PN) stage is the ultimate fate of stars with mass 1 to 8 solar masses (M). The origin of their complex morphologies is poorly understood, although sev…
Modelling the spectral energy distribution of the red giant in RS Ophiuchi: evidence for irradiation
Ya. V. Pavlenko, B. Kaminsky, M. T. Rushton +6
We present an analysis of optical and infrared spectra of the recurrent nova RS Oph obtained during between 2006 and 2009. The best fit to the optical spectrum for 2006 September 2…
