It has been asserted that the primary star in the HD 189733 system steadily accretes evaporated exospheric gases from its “hot Jupiter” companion, rather like a T Tauri star accreting from a disk. We conduct statistical and periodogram analyses of the photometric time series of the primary, as acquired by the automated photoelectric telescope, Microvariability and Oscillations of Stars, and Wise Observatory, to investigate this claim with the goal of revealing the presence of accretion shocks… 
Hot Jupiters accreting onto their parent stars: Effects on the stellar activity
Present Address Hot Jupiters (HJs) are massive gaseous planets orbiting close to their host stars. Due to their physical characteristics and proximity to the central star, HJs are the natural


Accretion onto Pre-Main-Sequence Stars
Accretion through circumstellar disks plays an important role in star formation and in establishing the properties of the regions in which planets form and migrate. The mechanisms by which
X-ray spectroscopy of stars
Non-degenerate stars of essentially all spectral classes are soft X-ray sources. Their X-ray spectra have been important in constraining physical processes that heat plasma in stellar environments to
Stellar activity of planetary host star HD 189 733
Aims. Extra-solar planet search programs require high-precision velocity measurements. They need to determine how to differentiate between radial-velocity variations due to Doppler motion and the
A Rich Cluster of Radio Stars in the rho Ophiuchi Cloud Cores
Deep 6 cm VLA observations of the central regions of the ρ Ophiuchi star-forming cloud reveal a concentration of faint stellar radio sources. A sensitivity better than 0.09 mJy is achieved,
Simultaneous Extreme-Ultraviolet Explorer and Optical Observations of Ad Leonis: Evidence for Large Coronal Loops and the Neupert Effect in Stellar Flares
We report on the first simultaneous Extreme-Ultraviolet Explorer (EUVE) and optical observations of flares on the dMe flare star AD Leonis. The data show the following features: (1) Two flares (one

X-ray quasi-periodic pulsations in solar flares as magnetohydrodynamic oscillations
We report the first observation at high spatial resolution of long-period quasi-periodic pulsations (QPP) of X-ray radiation during solar flares, made possible with the Reuven Ramaty High Energy
MOVES – I. The evolving magnetic field of the planet-hosting star HD189733
HD189733 is an active K dwarf that is, with its transiting hot Jupiter, among the most studied exoplanetary systems. In this first paper of the Multiwavelength Observations of an eVaporating
ELODIE metallicity-biased search for transiting Hot Jupiters. II. A very hot Jupiter transiting the bright K star HD 189733
Among the 160 known exoplanets, mainly detected in large radial-velocity surveys, only 8 have a characterization of their actual mass and radius thanks to the two complementary methods of detection:
The Evolution of Protostars: Insights from Ten Years of Infrared Surveys with Spitzer and Herschel
Stars form from the gravitational collapse of dense molecular cloud cores. In the protostellar phase, mass accretes from the core onto a protostar, likely through an accretion disk, and it is during
