    Greaves, Jane Sophia; Kennedy, G. M.; Thureau, N.; Eiroa, C.; Marshall, J. P.; Maldonado, J.; Matthews, B. C.; Olofsson, G.; Barlow, M. J.; Moro-Martin, A.; Sibthorpe, B.; Absil, O.; Ardila, D. R.; Booth, M.; Broekhoven-Fiene, H.; Brown, David John Alexander; Collier Cameron, A.; del Burgo, C.; Di Francesco, J.; Duchene, G.; Eisloffel, J.; Ertel, S.; Holland, W. S.; Horner, J.; Kalas, P.; Kavelaars, J. J.; Lestrade, J. -F.; Vican, L.; Wilner, D. J.; Wolf, S.; Wyatt, M. C. (2014-02-11) - Journal article
    Many nearby main-sequence stars have been searched for debris using the far-infrared Herschel satellite, within the DEBRIS, DUNES and Guaranteed-Time Key Projects. We discuss here 11 stars of spectral types A–M where the ...
  • Correlations between the stellar, planetary, and debris components of exoplanet systems observed by Herschel 

    Marshall, J.P.; Moro-Martín, A.; Eiroa, C.; Kennedy, G.; Mora, A.; Sibthorpe, B.; Lestrade, J.-F.; Maldonado, J.; Sanz-Forcada, J.; Wyatt, M.C.; Matthews, B.; Horner, J.; Montesinos, B.; Bryden, G.; Del Burgo, C.; Greaves, J.S.; Ivison, R.J.; Meeus, G.; Olofsson, G.; Pilbratt, G.L.; White, G.J. (2014-05-01) - Journal article
    Context. Stars form surrounded by gas-and dust-rich protoplanetary discs. Generally, these discs dissipate over a few (3-10) Myr, leaving a faint tenuous debris disc composed of second-generation dust produced by the ...
  • Does the presence of planets affect the frequency and properties of extrasolar Kuiper belts? Results from the Herschel DEBRIS and DUNES surveys 

    Moro-Martín, A.; Marshall, J.P.; Kennedy, G.; Sibthorpe, B.; Matthews, B.C.; Eiroa, C.; Wyatt, M.C.; Lestrade, J.-F.; Maldonado, J.; Rodriguez, D.; Greaves, J.S.; Montesinos, B.; Mora, A.; Booth, M.; Duchêne, G.; Wilner, D.; Horner, J. (2015-03-10) - Journal article
    The study of the planet-debris disk connection can shed light on the formation and evolution of planetary systemsand may help "predict" the presence of planets around stars with certain disk characteristics. In preliminary ...
  • A gas density drop in the inner 6 AU of the transition disk around the Herbig Ae star HD 139614 : Further evidence for a giant planet inside the disk? 

    Carmona, A.; Thi, W. F.; Kamp, I.; Baruteau, C.; Matter, A.; van den Ancker, M.; Pinte, C.; Kóspál, A.; Audard, M.; Liebhart, A.; Sicilia-Aguilar, A.; Pinilla, P.; Regály, Zs.; Güdel, M.; Henning, Th.; Cieza, L. A.; Baldovin-Saavedra, C.; Meeus, G.; Eiroa, C. (2017-02) - Journal article
    Context. Quantifying the gas surface density inside the dust cavities and gaps of transition disks is important to establish their origin. Aims. We seek to constrain the surface density of warm gas in the inner disk of HD ...
  • Gas lines from the 5-Myr old optically thin disk around HD 141569A Herschel observations and modeling 

    Thi, W.-F.; Pinte, C.; Pantin, E.; Augereau, J.C.; Meeus, G.; Ménard, F.; Martin-Zaïdi, C.; Woitke, P.; Riviere-Marichalar, P.; Kamp, I.; Carmona, A.; Sandell, G.; Eiroa, C.; Dent, W.; Montesinos, B.; Aresu, G.; Meijerink, R.; Spaans, M.; White, G.; Ardila, D.; Lebreton, J.; Mendigutía, I.; Brittain, S. (2014-01) - Journal article
    Context. The gas- and dust dissipation processes in disks around young stars remain uncertain despite numerous studies. At the distance of ~99–116 pc, HD 141569A is one of the nearest HerbigAe stars that is surrounded by ...
  • GW Orionis : inner disk readjustments in a triple system 

    Fang, M.; Sicilia-Aguilar, A.; Roccatagliata, V.; Fedele, D.; Henning, Th.; Eiroa, C.; Müller, A. (2014-10) - Journal article
    (abridged) We study the young stellar system GW Ori, concentrating on its accretion/wind activity by using our high-resolution optical spectra and U-band photometry. We also characterize the disk properties of GW Ori by ...
  • Nature of the gas and dust around 51 Ophiuchi : modelling continuum and Herschel line observations 

    Thi, W.F.; Ménard, F.; Meeus, G.; Carmona, A.; Riviere-Marichalar, P.; Augereau, J.-C.; Kamp, I.; Woitke, P.; Pinte, C.; Mendigutía, I.; Eiroa, C.; Montesinos, B.; Britain, S.; Dent, W. (2013-09-12) - Journal article
    Context. Circumstellar disc evolution is paramount for the understanding of planet formation. The gas in protoplanetary discs large program (GASPS) aims at determining the circumstellar gas and solid mass around ~250 ...
  • A network of filaments detected by Herschel in the Serpens core : a laboratory to test simulations of low-mass star formation 

    Roccatagliata, V.; Dale, J. E.; Ratzka, T.; Testi, L.; Burkert, A.; Koepferl, Christine Maria; Sicilia-Aguilar, Aurora; Eiroa, C.; Gaczkowski, B. (2015-12) - Journal article
    Context. Filaments represent a key structure during the early stages of the star formation process. Simulations show that filamentary structures commonly formed before and during the formation of cores. Aims. The Serpens ...
