PLANET II: A Microlensing and Transit Search for Extrasolar Planets
Penny D. Sackett, M. D. Albrow, J. -P. Beaulieu +16
Due to their extremely small luminosity compared to the stars they orbit, planets outside our own Solar System are extraordinarily difficult to detect directly in optical light. Ca…
Near-Field Microlensing and Its Effects on Stellar Transit Observations by Kepler
Kailash C. Sahu, Ronald L. Gilliland
In this paper, we explore the astrophysical implications of near-field microlensing and its effects on stellar transit observations, with a special emphasis on the Kepler mission.…
Determination of Substellar Mass Function of Young Open Clusters Using 2MASS and GSC Data
Anandmayee Tej, Kailash C. Sahu, T. Chandrasekhar +1
We present a statistical method to derive the mass functions of open clusters using sky survey data such as the 2 Micron All Sky Survey and the Guide Star Catalogue. We have used t…
The Spatially-Resolved Mass Function of the Globular Cluster M22
Michael D. Albrow, Guido De Marchi, Kailash C. Sahu
HST imaging of M22 has allowed, for the first time, a detailed and uniform mapping of mass segregation in a globular cluster. Luminosity and mass functions from the turnoff down to…
Substellar Mass Function of Young Open Clusters as Determined through a Statistical Approach Using 2MASS and GSC Data
Anandmayee Tej, Kailash C. Sahu, T. Chandrasekhar +1
In this paper we present the mass functions in the substellar regime of three young open clusters, IC 348, Orionis and Pleiades, as derived using the data from the 2 Micron All…
A Short, Non-Planetary, Microlensing Anomaly: Observations and Lightcurve Analysis of MACHO 99-BLG-47
M. D. Albrow, J. An, J. -P. Beaulieu +17
We analyze PLANET and MACHO observations of MACHO 99-BLG-47, the first nearly-normal microlensing event for which high signal-to-noise-ratio data reveal a well-covered, short-durat…
Revised Coordinates and Proper Motions of the Stars in the Luyten Half-Second Catalogue
Gaspar A. Bakos, Kailash C. Sahu, Peter Nemeth
We present refined coordinates and proper motion data for the high proper motion (HPM) stars in the Luyten Half-Second (LHS) catalogue. The positional uncertainty in the original L…
