Impact of photometric variability on age and mass determination of Young Stellar Objects: A case study on Orion Nebula Cluster
Sergio Messina, Padmakar S. Parihar, Elisa Distefano
In case of pre-main sequence objects, the only way to determine age and mass is by fitting theoretical isochrones on color-magnitude (alternatively luminosity-temperature) diagrams…
Physical parameters and long-term photometric variability of V1481 Ori, a SB2 member of Orion Nebula Cluster with an accreting component
Sergio Messina, Padmakar Parihar, Katia Biazzo +5
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 i…
An unusual very low-mass high-amplitude pre-main sequence periodic variable
Maria V. Rodriguez-Ledesma, Reinhard Mundt, Mansur Ibrahimov +5
We have investigated the nature of the variability of CHS7797, an unusual periodic variable in the Orion Nebula Cluster. An extensive I-band photometric data set of CHS7797 was com…
FR Cnc Revisited: Photometry, Polarimetry and Spectroscopy
A. Golovin, M. C. Galvez-Ortiz, M. Hernan-Obispo +12
Here we present the study of FR Cnc, a young, active and spotted star. We performed analysis of ASAS-3 (The All Sky Automated Survey) data for the years 2002-2008 and amended the v…
RACE-OC Project: Rotation and variability in the open cluster M11 (NGC6705)
S. Messina, P. Parihar, J. -R. Koo +3
Rotation and magnetic activity are intimately linked in main-sequence stars of G or later spectral types. The presence and level of magnetic activity depend on stellar rotation, an…
Exploring pre-main sequence variables of ONC: The new variables
Padmakar Parihar, Sergio Messina, Elisa Distefano +2
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…
