K 1-6 is a photoionised ISM nebula shaped by a fast-moving hot white dwarf in a triple system
Jaroslav Merc, David Jones, Ana Escorza +22
The study shows that nebula K 1‑6 is not a planetary nebula but interstellar gas photoionised by an evolved hot white dwarf, and that its central star is a hierarchical triple syst…
Observing bright pulsating white dwarfs with PLATO: A new window into the late stages of stellar evolution
Murat Uzundag, Alejandro H. Corsico, Nicholas Jannsen +17
We present the scientific case for exploiting the capabilities of the PLATO mission to study bright pulsating white dwarfs across a wide spectral range, including hydrogen-deficien…
Kepler Discovery of GW Vir Pulsations of the Central Star of Planetary Nebula Kn 61
Paulina Sowicka, Gerald Handler, J. J. Hermes +1
We report the discovery of pulsations in the N-rich PG 1159-type central star of the planetary nebula Kn 61 based on one month of Kepler Short Cadence observations. We detect four…
Classifying white dwarfs from multi-object spectroscopy surveys with machine learning
James Munday, Pier-Emmanuel Tremblay, Ingrid Pelisoli +5
With tens to hundreds of spectra of white dwarfs being taken each night from multi-object spectroscopic surveys, automated spectral classification is essential as part of efficient…
Appraising the Necklace: A post-common-envelope carbon dwarf inside an apparently carbon-poor planetary nebula
David Jones, Romano L. M. Corradi, Gustavo A. GarcÃa Pérez +15
Context: The Necklace nebula is a bipolar, post-common-envelope planetary nebula, the central star of which has been shown to have a dwarf carbon star companion. Aims: We aim to un…
Spectral evolution of hot hybrid white dwarfs: II. Photometry
Semih Filiz, Nicole Reindl, David Jones +4
We present a photometric analysis of 19 DA and 13 DAO white dwarfs (WDs) with effective temperatures exceeding 60 kK, building on the spectral analysis reported in the first paper…
