The magnetic field and magnetosphere of Plaskett's star: a fundamental shift in our understanding of the system
Wade, G. A.; Neiner, C.; Alecian, E. +7 more
Plaskett's 'star' appears to be one of a small number of short-period binary systems known to contain a hot, massive, magnetic star. We combine an extensive spectropolarimetric (Stokes V) data set with archival photometry and spectropolarimetry to establish the essential characteristics of the magnetic field and magnetosphere of the rapidly rotati…
Sub-stellar companions of intermediate-mass stars with CoRoT: CoRoT-34b, CoRoT-35b, and CoRoT-36b
Alonso, R.; Bouchy, F.; Deleuil, M. +18 more
Theories of planet formation give contradicting results of how frequent close-in giant planets of intermediate mass stars (IMSs; $1.3\le M_{\star }\le 3.2\, \mathrm{M}_{\odot }$) are. Some theories predict a high rate of IMSs with close-in gas giants, while others predict a very low rate. Thus, determining the frequency of close-in giant planets o…
CoRoT-TESS eclipsing binaries with light-travel-time effect
Bódi, A.; Hajdu, T.; Matécsa, B. +1 more
Identifying long-period eclipsing binaries with space-based photometry is still a challenge even in the century of space telescopes due to the relatively short observation sequences and short lifetime of these missions. The Transiting Exoplanet Survey Satellite (TESS) space telescope is an appropriate tool to supplement previous space-based observ…
Blackbody Temperature of 200+ Stellar Flares Observed with the CoRoT Satellite
Rabello Soares, M. Cristina; de Freitas, Marcia C.; Ferreira, Bernardo P. L.
We estimated blackbody temperature for 209 flares observed at 69 F-K stars, significantly increasing the number of flare temperature determinations. We used the Blue and Red channels obtained by the 27 cm telescope of the CoRoT satellite at high cadence and long duration. The wavelength limits of the channels were estimated using spectra from the …
