Planet Hunters IX. KIC 8462852 - where's the flux?
Over the duration of the Kepler mission, KIC 8462852 was observed to undergo irregularly shaped, aperiodic dips in flux of up to ˜20 per cent. The dipping...
Planet Hunters TESS II: findings from the first two years of TESS
We present the results from the first two years of the Planet Hunters TESS (PHT) citizen science project, which identifies planet candidates in the TESS...
Planet Hunters TESS IV: a massive, compact hierarchical triple star system TIC 470710327
We report the discovery and analysis of a massive, compact, hierarchical triple system (TIC 470710327) initially identified by citizen scientists in data...
Planetary nebulae as tracers of galaxy stellar populations
We address the general problem of the luminosity-specific planetary nebula (PN) number, better known as the `α' ratio, given by α=NPN/Lgal, and its relationship...
Planetary nebulae hosting accreting white dwarfs: a possible solution for the mysterious cut-off of planetary nebula luminosity function?
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...
We analyse the planetary nebulae (PNe) population of the Small Magellanic Cloud (SMC), based on evolutionary models of stars with metallicities in the range 10...
Planetary nebulae: the universal mass-metallicity relation for Local Group dwarf galaxies and the chemistry of NGC 205
Here we study 16 planetary nebulae (PNe) in the dwarf irregular galaxy NGC 205 by using Gemini Multi-Object Spectrographs (GMOS@Gemini) spectra to derive their...
Planetary system detection by estimating the covariance of coronagraphic lucky images
In this paper, we review two different methods to increase image contrast and propose the combination of both to detect faint companions surrounding a host star...
Polarimetry of the transient relativistic jet of GRB 110328/Swift J164449.3+573451
We present deep infrared (Ks-band) imaging polarimetry and radio (1.4- and 4.8-GHz) polarimetry of the enigmatic transient Swift J164449.3+573451. This source...
