CHIPS: The Carina High-contrast Imaging Project of massive Stars [PDF]

open access: yes, 2016
The formation of massive stars remains one of the most intriguing questions in astrophysics today. The main limitations result from the difficulty to obtain direct observational constraints on the formation process itself.

RADIOMA Project (IOnizing RADiation in MAmmography): an Italian proposal for the development of an innovative dose index in mammography

open access: yes, 2018
The University of Pisa has a long-standing experience in the field of radiation protection. Therefore, it is not surprising that the University of Pisa Radiology team actively participated to all editions of EuroSafe Imaging poster sessions at the ECR,

Magnetic Doppler imaging of early-type stars

open access: yes, 2010
Doppler imaging of early-type magnetic stars is the most advanced method to interpret their line profile variations. DI allows us to study directly a complex interplay between chemical spots, magnetic fields, and the mass loss.

The magnetic activity, winds and planets of young, cool stars [PDF]

open access: yes, 2018
This thesis uses spectropolarimetry to observationally investigate the properties of dynamos and winds of young cool stars, and search for young planets.

Doppler imaging of active young stars

open access: yes, 2011
This thesis investigates the activity of three young solar analogues, R58, LQ Lup, and RX J0850.1-7554, using Doppler imaging, as a way to investigate the early history of solar activity by proxy.

Doppler and Zeeman Doppler Imaging of Stars

open access: yes, 2016
In this chapter we discuss the problem of reconstructing two-dimensional stellar surface maps from the variability of intensity and/or polarisation profiles of spectral lines.

Medical Magic and the Church in Thirteenth-Century England

open access: yesSocial history of medicine: The journal of the Society for the Social History of Medicine, 2011
‘Do you know any incantation for fevers and for any illness, which is called a blessing?’1 This was one of several questions relating to magic (sortilegium) that the early thirteenth–century scholar John of Kent suggested that priests could ask penitents

Hot Stars with Cool Companions [PDF]

open access: yes, 2014
We present intermediate results of a spectroscopic survey for late K-M companions orbiting nearby A and B type stars. Such companions may have formed in the massive disk of the young primary star, and so may be scaled-up versions of brown dwarfs formed ...
