    • Accretion discs as regulators of stellar angular momentum evolution in the ONC and Taurus-Auriga 

      Davies, Claire; Gregory, Scott; Greaves, Jane Sophia (2014-10-21) - Journal article
      In light of recent substantial updates to spectral type estimations and newly established intrinsic colours, effective temperatures, and bolometric corrections for pre-main sequence (PMS) stars, we re-address the theory ...
    • Alignment in star-debris disc systems seen by Herschel 

      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 ...
    • Consistent dust and gas models for protoplanetary disks I. Disk shape, dust settling, opacities, and PAHs 

      Woitke, Peter; Min, M.; Pinte, C.; Thi, W. -F.; Kamp, I.; Rab, C.; Anthonioz, F.; Antonellini, S.; Baldovin-Saavedra, C.; Carmona, A.; Dominik, C.; Dionatos, O.; Greaves, Jane Sophia; Güdel, M.; Ilee, John David; Liebhart, A.; Ménard, F.; Rigon, Laura; Waters, L. B. F. M.; Aresu, G.; Meijerink, R.; Spaans, M. (2016-02-02) - Journal article
      We propose a set of standard assumptions for the modelling of Class II and III protoplanetary disks, which includes detailed continuumradiative transfer, thermo-chemical modelling of gas and ice, and line radiative transfer ...
    • The environments in which stars and circumstellar discs form 

      Poulton, Christopher John (University of St Andrews, 2008) - Thesis
      In this thesis, images of a debris disc are used to examine the evidence for the presence of a Neptune-like planet around ε Eridani and detections of protoplanetary discs are used to investigate the evidence for star and ...
    • Extreme conditions in a close analog to the young solar system : Herschel observations of ∈ Eridani 

      Greaves, Jane Sophia; Sibthorpe, B.; Acke, B.; Pantin, E. E.; Vandenbussche, B.; Olofsson, G.; Dominik, C.; Barlow, M. J.; Bendo, G. J.; Blommaert, J. A. D. L.; Brandeker, A.; de Vries, B. L.; Dent, W. R. F.; Di Francesco, J.; Fridlund, M.; Gear, W. K.; Harvey, P. M.; Hogerheijde, M. R.; Holland, W. S.; Ivison, R. J.; Liseau, R.; Matthews, B. C.; Pilbratt, G. L.; Walker, H. J.; Waelkens, C. (2014-08-10) - Journal article
      Far-infrared Herschel images of the Eridani system, seen at a fifth of the Sun's present age, resolve two belts of debris emission. Fits to the 160 μm PACS image yield radial spans for these belts of 12-16 and 54-68 AU. ...
    • Interferometry and the study of protoplanetary disks 

      Ilee, John David; Greaves, Jane Sophia (2015-09-23) - Journal article
      Interferometry offers access to scales that are unresolvable using single dish telescopes, which is especially important when investigating objects with small angular sizes, such as protoplanetary disks. This Chapter ...
    • Life at the end of worlds : modelling the biosignatures of microbial life in diverse environments at the end of the habitable lifetimes of Earth-like planets 

      O'Malley-James, Jack T. (University of St Andrews, 2014-12-01) - Thesis
      This thesis investigates how increased global mean temperatures on Earth, induced by the increase in the luminosity of the Sun as it ages, change the types of habitable environments on the planet at local scales over the ...
    • Signatures of warm carbon monoxide in protoplanetary discs observed with Herschel SPIRE 

      van der Wiel, M. H. D.; Naylor, D. A.; Kamp, I.; Ménard, F.; Thi, W.-F.; Woitke, Peter; Olofsson, G.; Pontoppidan, K. M.; Di Francesco, J.; Glauser, A. M.; Greaves, Jane Sophia; Ivison, R. J. (2014-11-11) - Journal article
      Molecular gas constitutes the dominant mass component of protoplanetary discs. To date, these sources have not been studied comprehensively at the longest far-infrared and shortest submillimetre wavelengths. This paper ...
