We acquired 114 new BV observations of HR 7355 at observatories in Arizona, U.S.A and Cape Town, South Africa. We performed period analyses of the new observations along with new analyses of 732 archival measurements from the Hipparcos and ASAS projects. We find that the light curves of HR 7355; in various filters are quite similar, double-peaked, with unevenly deep minima. We substantially refine the rotational period to be P = 0.5214410(4)d, indicating that HR 7355gt; is the most rapidly…

Magnetic field detection in the B2 Vn star HR 7355

The B2Vn star HR 7355 is found to be a He-rich magnetic star. Spectropolarimetric data were obtained with FORS1 at UT2 on Paranal Observatory to measure the disc-averaged longitudinal magnetic field

The rapid magnetic rotator HR 7355†

Abstract For early type magnetic stars slow, at most moderate rotational velocities have been considered an observational fact. The detection of a multi-kilogauss magnetic field in the B2Vpn star


The SDSS III APOGEE survey recently identified two new σ Ori E type candidates, HD 345439 and HD 23478, which are a rare subset of rapidly rotating massive stars whose large (kGauss) magnetic fields

Discovery of a strong magnetic field in the rapidly rotating B2Vn star HR 7355

Abstract We report on the detection of a strong, organized magnetic field in the helium-variable early B-type star HR 7355 using spectropolarimetric data obtained with ESPaDOnS on CFHT by the MiMeS

Surprising variations in the rotation of the chemically peculiar stars CU Virginis and V901 Orionis

CU Vir and V901 Ori belong among these few magnetic chemically peculiar stars whose rotation periods vary on timescales of decades. We aim to study the stability of the periods in CU Vir and V901 Ori

The period evolution of the chemically peculiar star V473 Tau

In this paper, the period evolution of the rotating chemically peculiar star V473 Tau (A0Si, V=7.26 mag) is investigated. Even though the star has been observed for more than fifty years, for the

An investigation of four chemically peculiar stars with photometric periods below 12 h

We present an investigation of three chemically peculiar (CP) stars and one CP star candidate that exhibit photometric periods below 12 h. New spectroscopic observations have been acquired that

K2 observations of 95 Vir: δ Scuti pulsations in a chromospherically active star

We have searched for photometric variability in 95 Vir, a fast rotating, chromospherically active early F-type star, which was observed in the framework of Campaign 6 of the Kepler K2 mission.

Photometric Variability of the mCP Star CS Vir: Evolution of the Rotation Period

Abstract The aim of this study is to accurately calculate the rotational period of CS Vir by using STEREO observations and investigate a possible period variation of the star with the help of all



The most rapidly rotating He-strong emission line star: HR 7355
