Lessons from the Ionised and Molecular Mass of Post-CE PNe
Galaxies, 2022 Close binary evolution is widely invoked to explain the formation of axisymmetric planetary nebulae after a brief common envelope phase. The evolution of the primary would be interrupted abruptly, its still quite massive envelope being fully ejected to ...

The post-common-envelope, binary central star of the planetary nebula Hen 2-11 [PDF]
Astronomy & Astrophysics, 2014 We present a detailed photometric study of the central star system of the planetary nebula Hen 2-11, selected for study because of its low-ionisation filaments and bipolar morphology - traits which have been strongly linked with central star binarity.

Planetary nebula progenitors that swallow binary systems
, 2015 I propose that some irregular `messy' planetary nebulae owe their morphologies to triple-stellar evolution where tight binary systems evolve inside and/or on the outskirts the envelope of asymptotic giant branch (AGB) stars.

Binary Black Hole Mergers: Formation and Populations
Frontiers in Astronomy and Space Sciences, 2020 We review the main physical processes that lead to the formation of stellar binary black holes (BBHs) and to their merger. BBHs can form from the isolated evolution of massive binary stars.

, 2015 We propose a scenario for the formation of the pulsar with two white dwarfs (WDs) triple system PSR J0337+1715. In our scenario a close binary system is tidally and frictionally destroyed inside the envelope of a massive star that later goes through an ...

The impact of binary-star yields on the spectra of galaxies [PDF]
, 2009 One of the complexities in modelling integrated spectra of stellar populations is the effect of interacting binary stars besides Type Ia supernovae (SNeIa).

The Astronomical JournalWe provide a detailed characterization of 2M07515777+1807352, a post-common-envelope eclipsing binary system with a 10.3-day, nearly (but not quite) circular orbit ( e = 0.02).

Hot subdwarf formation: Confronting theory with observation
EPJ Web of Conferences, 2013 The formation of hot subdwarf stars is still unclear. Both single-star and binary scenarios have been proposed to explain the properties of these evolved stars situated at the extreme blue end of the horizontal branch. The observational evidence gathered

Wolf-Rayet stars in the Small Magellanic Cloud as testbed for massive star evolution
, 2018 The majority of Wolf-Rayet (WR) stars represent the stripped cores of evolved massive stars who lost most of their hydrogen envelope. In low metallicity environments, such as the Small Magellanic Cloud (SMC), stellar winds are weaker and binary ...

Surface Tension Measurement of Ti‐6Al‐4V by Falling Droplet Method in Oxygen‐Free Atmosphere
Advanced Engineering Materials, EarlyView.In this article, the temperature‐dependent surface tension of free falling, oscillating Ti‐6Al‐4V droplets is investigated in both argon and monosilane doped, oxygen‐free atmosphere. Droplet temperature and oscillation are captured with one single high‐speed camera, and the surface tension is calculated with Rayleigh's formula.
