  • ARCO: a program for Automatic Reduction of CCD Observations 
    Distefano, E; Messina, S; Cutispoto, G; Parihar, P. S; Comparato, M; Busá, I; Lanza, A. F; Lanzafame, A. C; Pagano, I; Strassmeier, K. G (EDP Sciences, 2007)
    The huge amount of CCD photometric data collected by robotic telescopes (as for instance the ICE-T telescope to be installed at Dome-C) requires a fully automated approach to the reduction and analysis procedures. To this ...
  • Exploring pre-main sequence variables of ONC: the new variables 
    Parihar, P. S; Messina, S; Distefano, E; Shantikumar, N. S; Medhi, B. J (Wiley Blackwell, 2009-07)
    Since 2004, we have been engaged in a long-term observing program to monitor young stellar objects in the Orion Nebula Cluster. We have collected about two thousands frames in V, R, and I broad-band filters on more than ...
  • Impact of photometric variability on age and mass determination in young stellar objects: the case of the Orion Nebula Cluster 
    Messina, S; Parihar, P. S; Distefano, E (IOP Publishing, 2017-06)
    Very young stars, like the Orion Nebula Cluster (ONC) members analysed in the present study, exhibit photometric variability with a wide range of amplitudes. Such a prominent variability reflects in the inferred values of ...
  • Physical parameters and long-term photometric variability of V1481 Ori, an SB2 member of Orion nebula Cluster with an accreting component 
    Messina, S; Parihar, P. S; Biazzo, K; Lanza, A. F; Distefano, E; Melo, C. H. F; Bradstreet, D. H; Herbst, W (Oxford University Press on behalf of the Royal Astronomical Society, 2016-04)
    We present the results of our analysis on V1481 Ori (JW 239), a young SB2 in the Orion nebula Cluster with a circumbinary disc accreting on the lower mass component. The analysis is based on high-resolution spectroscopic ...
  • The RACE-OC project: Rotation and ACtivity Evolution in Open Clusters 
    Messina, S; Distefano, E; Parihar, P. S; Busa, I; Cutispoto, G; Lanza, A.F; Lanzafame, A; Pagano, I; Biazzo, K; Leto, G; Hatzidimitriou, D; Kim, S. -L; Koo, J. -R; Kang, Y. B (American Institute of Physics, 2009)
    The RACE‐OC project, standing for Rotation and Activity Evolution in Open Clusters, is a long‐term project aimed at studying the evolution of rotation and magnetic activity of late‐type members of stellar open clusters. ...
  • RACE-OC project: rotation and variability in the open cluster NGC 2099 (M 37) 
    Messina, S; Distefano, E; Parihar, P. S; Kang, Y. B; Kim, S. -L; Rey, S. -C; Lee, C. -U (EDP Sciences, 2008-05)
    Context. Rotation and solar-type magnetic activity are closely related to each other in main-sequence stars of G or later spectral types. The presence and level of magnetic activity depend on star's rotation, and rotation ...
