Rotation periods for very low mass stars in the Pleiades
We present the results of a photometric monitoring campaign for very low mass (VLM) members of the Pleiades. Periodic photometric variability was detected for nine VLM stars with masses between 0.08 and 0.25 M⊙. These variations are most likely caused by co-rotating, magnetically induced spots. In comparison with solar-mass stars, the photometric amplitudes are very low (< 0.04mag), implying th...
متن کاملPre-Main-Sequence Stars with Photometric Rotation Periods
We use mid-IR (primarily 10 μm) photometry as a diagnostic for the presence of disks with inner cavities among 32 pre-main sequence stars in Orion and Taurus-Auriga for which rotation periods are known and which do not show evidence for inner disks at near-IR wavelengths. Disks with inner cavities are predicted by magnetic disk-locking models that seek to explain the regulation of angular momen...
متن کاملRotation periods of exoplanet host stars
The stellar rotation periods of 10 exoplanet host stars have been determined using newly analysed Ca II H&K flux records from the Mount Wilson Observatory and Strömgren b, y photometric measurements from Tennessee State University’s automatic photometric telescopes at the Fairborn Observatory. Five of the rotation periods have not previously been reported, with that of HD 130322 very strongly d...
متن کاملRotation periods for very low mass stars in Praesepe
We investigate the rotation periods of fully convective very low mass stars (VLM, M < 0.3M⊙), with the aim to derive empirical constraints for the spindown due to magnetically driven stellar winds. Our analysis is based on a new sample of rotation periods in the main-sequence cluster Praesepe (age 600Myr). From photometric lightcurves obtained with the Isaac Newton Telescope, we measure rotatio...
متن کاملChromospheric activity and rotation of FGK stars in the solar vicinity ***
Context. Chromospheric activity produces both photometric and spectroscopic variations that can be mistaken as planets. Large spots crossing the stellar disc can produce planet-like periodic variations in the light curve of a star. These spots clearly affect the spectral line profiles, and their perturbations alter the line centroids creating a radial velocity jitter that might “contaminate” th...
