摘要:Abstract(#br)We have used spectrophotometric data from nine Hubble Space Telescope orbits to eclipse-map the primary component of the RS CVn binary SV Cam. From these observations and its HIPPARCOS parallax we find that the surface flux in the eclipsed low-latitude region is...

摘要:Abstract(#br)The lined chiton Tonicella lineata (Wood, 1815) is found on enerusting coralline algae in the lower rocky intertidal zone of Oregon and San Juan Island, Washington, USA. An encrusting coralline alga is the major food item of this chiton. Experiments were performed to...

摘要:Abstract(#br)A new directionally sensitive velocity measurement system based upon a single oscillating hot-wire probe has been developed. The vibration of the hot-wire was effected by a piezoelectric oscillator that could be driven at different amplitudes and frequencies. The sig...

摘要:ABSTRACT(#br)We present the first results from our Red Optical Planet Survey to search for low‐mass planets orbiting late‐type dwarfs (M5.5V–M9V) in their habitable zones. Our observations with the red arm of the Magellan Inamori Kyocera Echelle spectrograph (0.5–0.9 m)...

摘要:ABSTRACT(#br)This paper is part of a multiwavelength study aimed at using complementary photometric, polarimetric and spectroscopic data to achieve an understanding of the activity process in late‐type stars. Here, we present the study of FR Cnc, a young, active and spotted ...

摘要:ABSTRACT(#br)We present an analysis of the photometric variability of M dwarfs in the Wide Field Camera (WFCAM) Transit Survey. Although periodic light‐curve variability in low mass stars is generally dominated by photospheric star spot activity, M dwarf variability in the J...

摘要:ABSTRACT(#br)We present Doppler images of the young K5V–K7V rapid rotator LO Peg from seven nights of continuous spectroscopy obtained in 1998 from July 04 to July 10. The images reveal the presence of a strong polar cap with appendages extending to mid‐latitudes, but no sta...

摘要:ABSTRACT(#br)We use signal enhancement techniques and a matched filter analysis to search for the K ‐band spectroscopic absorption signature of the close orbiting extrasolar giant planet, HD 189733b. With time‐series observations taken with the Near Infrared Spectrometer (NI...

摘要:ABSTRACT(#br)We have carried out a search for the 2.14‐μm spectroscopic signature of the close orbiting extrasolar giant planet, HD 179949b. High‐cadence time‐series spectra were obtained with the Cryogenic high‐resolution InfraRed Échelle Spectrograph at Very Larg...

摘要:Abstract(#br)We present high resolution Doppler images of the short period (P = 0.362 d) contact binary AE Phe. Using least squares deconvolution, we make use of the information content of the several thousand lines in each échelle spectrum to obtain the necessary S/N and ti...
