  • ALMA observations of the η Corvi debris disc: Inward scattering of CO-rich exocomets by a chain of 3-30 M⊕ planets? 

    Marino, S; Wyatt, MC; Panić, O; Matrà, L; Kennedy, GM; Bonsor, A; Kral, Q et al. (Oxford University Press, 2017-01-01)
    While most of the known debris discs present cold dust at tens of astronomical unit (au), a few young systems exhibit hot dust analogous to the Zodiacal dust. η Corvi is particularly interesting as it is old and it has ...
  • Exocometary gas in the HD 181327 debris ring 

    Marino, S; Matrà, L; Stark, C; Wyatt, MC; Casassus, S; Kennedy, G; Rodriguez, D et al. (Oxford University Press, 2016-05-23)
    An increasing number of observations have shown that gaseous debris discs are not an exception. However, until now, we only knew of cases around A stars. Here we present the first detection of 12CO (2-1) disc emission ...
  • ALMA Observations of the Debris Disk of Solar Analogue τ Ceti 

    MacGregor, MA; Lawler, SM; Wilner, DJ; Matthews, BC; Kennedy, GM; Booth, M; Francesco, JD (American Astronomical Society, 2016-09-10)
    We present 1.3 mm observations of the Sun-like star τ Ceti with the Atacama Large Millimeter/submillimeter Array that probe angular scales of (4 au). This first interferometric image of the τ Ceti system, which hosts both ...
  • Early science with the Large Millimetre Telescope: Deep LMT/AzTEC millimetre observations of ϵ Eridani and its surroundings 

    Chavez-Dagostino, M; Bertone, E; de Miera, FCS; Marshall, JP; Wilson, GW; Śanchez-Argüelles, D; Hughes, DH et al. (Oxford University Press, 2016-11-01)
    ϵ Eridani is a nearby, young Sun-like star that hosts a ring of cool debris analogous to the Solar system's Edgeworth-Kuiper belt. Early observations at (sub-)mm wavelengths gave tentative evidence of the presence of ...
