The impact of stellar metallicity on rotation and activity evolution in the Kepler field using gyro-kinematic ages
Victor See, Yuxi, Lu +2
In recent years, there has been a push to understand how chemical composition affects the magnetic activity levels of main sequence low-mass stars. Results indicate that more metal…
Further evidence of the link between activity and metallicity using the flaring properties of stars in the Kepler field
Victor See, Julia Roquette, Louis Amard +1
The magnetic activity level of low-mass stars is known to vary as a function of the physical properties of the star. Many studies have shown that the stellar mass and rotation are…
The influence of the environment on the spin evolution of low-mass stars. I. External photoevaporation of circumstellar disks
Julia Roquette, Sean P. Matt, Andrew J. Winter +2
Massive stars are strong sources of far-ultraviolet radiation that can be hostile to the evolution of protoplanetary disks, driving mass loss by external photoevaporation and short…
Star-disk interaction in the T Tauri star V2129 Oph: An evolving accretion-ejection structure
A. P. Sousa, J. Bouvier, S. H. P. Alencar +16
Classical T Tauri stars are young low-mass systems still accreting material from their disks. These systems are dynamic on timescales of hours to years. The observed variability ca…
Photometric variability as a proxy for magnetic activity and its dependence on metallicity
Victor See, Julia Roquette, Louis Amard +1
Understanding how the magnetic activity of low-mass stars depends on their fundamental parameters is an important goal of stellar astrophysics. Previous studies show that activity…
Evidence for Metallicity-Dependant Spin Evolution in the Kepler field
L. Amard, J. Roquette, S. P. Matt
A curious rotation period distribution in the Color-Magnitude-Period Diagram (CMPD) of the Kepler field was recently revealed, thanks to data from Gaia and Kepler spacecraft. It wa…
Near-infrared time-series photometry in the field of Cygnus OB2 association II. Mapping the variability of candidate members
J. Roquette, S. H. P. Alencar, J. Bouvier +2
We present the results of a J, H, and K photometric variability survey of the central 0.78 square degrees of the young OB association Cygnus OB2. We used data observed with the Wid…
Near-Infrared Time-Series Photometry in the Field of Cygnus OB2 Association I - Rotational Scenario For Candidate Members
J. Roquette, J. Bouvier, S. H. P. Alencar +2
In the last decades, the early pre main sequence stellar rotational evolution picture has been constrained by studies targeting different young regions at a variety of ages. Observ…
The VVV Templates Project. Towards an Automated Classification of VVV Light-Curves. I. Building a database of stellar variability in the near-infrared
R. Angeloni, R. Contreras Ramos, M. Catelan +50
Context. The Vista Variables in the Vía Láctea (VVV) ESO Public Survey is a variability survey of the Milky Way bulge and an adjacent section of the disk carried out from 2010 on E…
