Summary of the training activity and research achievements of the
Florence node during the third year of JETSET project



Progress made in the

area of training and transfer of knowledge


Dr. Deirdre Coffey
, the f;orence ER, has continued her work at the Arcetri node for
the second year of her contract. During this year her activity focused on studies of
rotation in jets in tracers at infrared
wavelengths, diagnostics of jet physics close to
the source from optical lines, and studies of disk kinematics at mm wavelengths.



She gave a talk about Rotation in Stellar Jets in Arcetri on September 2007: “ Stellar
Jets at High Angular Resolution”

and

collaborated with local PhD students and staff to the preparation of proposals for
observing time and the analysis of acquired data.


D.C. worked in Arcetri with R. Cesaroni regarding MAPPING software for

interferometric data reduction, in preparatio
n for visit to Grenoble. Subsequently she

visited Grenoble on April 2007 for two weeks to begin collaboration

to work on PdiBI interferometric data of FU Ori . There she gave a seminar on
rotation in jets.



D.C. participated to several conferences a
nd meetings to the purpose of exchanging

knowledges about observational astronomy and physical interpretation of the data:




Grenoble, IAU symp. n. 243 on star formation at LAOG in May 2007, at which
she presented a poster



Dublin, JETSET Observers Worksho
p, DIAS, May 2007



Noordwijk, ESA Headquarters, in May 2007, at which she gave a talk



Azores, 4
th

JETSET school, June 2007, at which she

presented a poster



Galway, 5
th

JETSET school and meeting, during which she gave a talk.



Bologna, conference “HST after

SM4”, where she presented two posters and

started a collaboration with A. Gomez de Castro of Madrid University on HST
UV observations.






Dr. Samira Rajabi,

ESR at the Porto node, is collaborating with the Florence node on
the subject of her PhD thesis.

She visited Flroence for two months in Feb

and susequently met and discussed with F. Bacciotti at the Azores and Galway
schools. She will have a secondment period in Florence during the next few months.

Observational proposals in collaboration


Several proposals to obtain observing time for JETSET science goals were submitted
from t
he Florence node in close collaboration with the Dublin, Rome, Paris and
Grenoble nodes and outside researchers. These proposals concern the kinematics of
the jets and the gas excitation in jet shocks, the rotation of molecular flows, the flows
from Brown
Dwarfs.

The proposals for the Plateau de Bure Interferometer, VLT/FORS,

VLT/ISAAC, GEMINI/GNIRS, JCMT, 30

m IRAM, and TNG/NICS

have been allocated the requested hours observing time, and most of the observations
were executed in service mode. C. Codel
la and F. Massi executed observations in
visitor mode at 30
-
m IRAM, and La Palma Observatory TNG, respectively.




Research achievements


Joint research projects regarding high angular resolution of Jets and their comparison
with Models are actively in

place with the nodes of Rome, Turin, Grenoble,

Tautenburg, Porto, Dublin. These led to a number of publications and scientific
exchanges as described in the following paragraphs.



The main scientific goals of the above collaborations have been:



Detection

and analysis of rotation in molecular jets at Near Infrared (with Dublin,
Tautenburg, Rome)



Spectral Diagnostics of stellar jets from optical lines at high angular resolution

(with Rome, Dublin, Tautenburg)

-

Determination of kinematics and structure o
f molecular outflows (with Paris,
Grenoble)



Angular Momentum transport in jets and disks (with Tautenburg, Dublin)



Determination of the structure of inner winds (with Grenoble)



mm
-
wav study of disk structure and kinematics from interferometric data (with

Grenoble)



Detection and spectroscopy of collimated jets from Brown Dwarfs (with Dublin)



Spectro
-

inf
low conditions



Numerical codes for H radiative transfer (with Porto)
