Here is a list of current and recent visitors to the Solar Theory Group.
Hiroaki has done some excellent work on flux emergence as past of his thesis and is presently spending a year at Cambridge working on magnetoconvection.
Thomas's main interests are in coronal magnetic field extrapolation, in particular the extrapolatiion of non-linear force-free fields.
Fernando Moreno Insertis
Fernando will be working with the emerging flux group during his stay.
Dr Klaus Galsgaard
Klaus will be working with the emerging flux group during the first week and the rest of us during the second week - on numerical stuff, of course!
Thomas is particularly interested in coronal magnetic field extrapolation. In Lindau he is working in the STEREO team.
He is a specialist in mhd waves
She is developing an MHD code for studying magneto-acoustic waves in sunspots. Presently the work has involved linear waves but is now looking to study non-linear effects.
Prof E N Parker
He is an expert on numerical mhd and instabilities and has been working recently on a reconnection simulation
Prof. Dave Walker
Dave is an expert on wave propagation and mode coupling in nonuniform media, including WKB analysis. He will give a seminar for the group.
Professor Yuzef Zhugzhda
Yuzef is well known for his many papers in solar MHD, especially connected with sunspots and with MHD waves. He is a forceful speaker and contributor at conferences! Formerly he was much involved with the Soviet space programme, but since his retirement he has spent several years in the Kiepenheuer Institute for Solar Physics, Freiberg, working with Prof Stix on such topics as p-modes in the presence of convection and MHD waves in thin flux tubes.
Dr Tongjiang Wang
Tongjiang is well known for his observations with SoHO/SUMER of oscillations in coronal loops.
Jim is interested in mhd waves, particle acceleration and inertial Alfven waves
Anastasia is interested in ion acceleration in substorms and numerical simulations. She will be visiting EPCC and St Andrews to enable her to parallelize a code to integrate ion trajectories in a collapsing magnetotail field.
Laura Bone and Ross Galloway
Laura and Ross have come to discuss the topology of magnetic fields and to find out more about magnetic modelling.
Dr P. Gallagher
Peter has spent 2 days in discussions with various member of the group, before giving the applied seminar.
Dr Brian Welsch
Following on from the small magnetic feature tracking workshop was held last year Brian has come over to discuss the identification and tracking of cancelling magnetic features in both active and quiet-sun regions.
Brian gave talks at both the Solar Group's seminar and at reconnection club.
Prof. M. Berger
Mitch spent a fruitful morning in discussion with Gunnar about helicity before giving the applied seminar.
Ms Selwa is working with Kris Murawski in numerical simulations of MHD waves in coronal loops. She has come over to discuss various aspects of her numerical simulations of waves propagation in non-homogeneous plasmas. Whilst here she has given 2 talks to the waves sub-group and a wednesday seminar to the solar group.
Dr. Mervyn Freeman
Mervyn and Thomas enjoyed many useful discussions on magnetotail models during his visits.
(1)Dr Craig DeForest, (2)Dr Mandy Hagenaar, (1)Derek Lamb and (3)Dr Brian Welsch
A small magnetic feature tracking workshop was held. At this workshop we all used our respective feature tracking codes to analyse the same data set. All our codes have different methods of identifing features and use different criteria for tracking. By analysing the same dataset we were able to determine the pros and cons of each code and identify what should be the 'best' overall approach to tracking magnetic features.
Craig DeForest gave the weeks Solar Group seminar highlighting the uses and pit falls of magnetic feature tracking.
Prof. Robert Rosner
Bob Rosner gave the week Applied Maths seminar to the School attracting a wide audience not only from Maths, but also Astronomy. He had discussion with various members of the solar group including, Bernie Roberts, Eric Priest, Ineke De Moortel and Clare Parnell.
Dr Dieter Nickeler (and his wife Michaela, an Astrophysicist)
Dieter has visited the Solar Group before (April this year) and is presently based at the University of Utrecht where he is working towards a PhD.
Dieter did his Diploma in Physics in Bochum, supervised by Karl Schindler. He first moved to the University of Bonn, working with Hans Fahr on the structure of the Heliosphere and has since moved to Utrecht where he continues this work. Dieter is especially interested in MHD states with flows, both ideal and non-ideal.
Dr Stephane Regnier
Stephane is an expert in numerical MHD, especially calculating nonlinear force-free fields of active regions - he is giving the group seminar on wednesday, but will also be free to speak to anyone who would like to during the week.
Stephane did his PhD with Tahar Amari and was then a postdoc in Montana, before moving to a postdoc position at Estec in Holland this year.
Dr Emmanuele Tassi
Emmanuele is visiting Eric and Gunnar to collaborate on a project looking for 3D reconnection solutions about null points.
Dr Gunnar Hornig
Research interests: Structure of magnetic fields, magnetic reconnection, magnetic helicity, topological invariants, topology and representation of electromagnetic fields, MHD.
Seminars and lectures given whilst at St Andrews: Informal lectures on "Magnetic Null Points" and "Magnetic Helicity", seminars on "Magnetic Reconnection"
