The interactive responses of fertigation levels under buried straw layer on growth, physiological traits and fruit yield in tomato plant

Journal of Plant Interactions, 2019
The experiments were conducted on tomato plants to study the interactive responses of water levels (W70%: 70% of water consumption and W90%: 90% water consumption) and nitrogen rates (N100%: 100% of recommended and N80%:80% of N1.0) under two straw ...

The luminous late-time emission of the type Ic supernova iPTF15dtg - evidence for powering from a magnetar? [PDF]

, 2018
iPTF15dtg is a Type Ic supernova (SN) showing a broad light curve around maximum light, consistent with massive ejecta if we assume a radioactive-powering scenario.

Machine Learning Techniques for Stellar Light Curve Classification [PDF]

, 2018
We apply machine learning techniques in an attempt to predict and classify stellar properties from noisy and sparse time series data. We preprocessed over 94 GB of Kepler light curves from MAST to classify according to ten distinct physical properties ...

Phase light curves for extrasolar Jupiters and Saturns [PDF]

, 2004
We predict how a remote observer would see the brightness variations of giant planets similar to Jupiter and Saturn as they orbit their central stars. We model the geometry of Jupiter, Saturn and Saturn's rings for varying orbital and viewing parameters.

The detailed optical light curve of GRB 030329 [PDF]

, 2004
(Abridged) We present densely sampled BVRI light curves of the optical transient associated with the gamma-ray burst GRB 030329, the result of a coordinated observing campaign conducted at five observatories. Augmented with published observations of this

The Orbital Light Curve of Aquila X-1 [PDF]

, 2000
We obtained R- and I-band CCD photometry of the soft X-ray transient/neutron- star binary Aql X-1 in 1998 June while it was at quiescence. We find that its light curve is dominated by ellipsoidal variations, although the ellipsoidal variations are ...

The Peculiar Type Ic Supernova 1997ef: Another Hypernova [PDF]

, 1998
SN 1997ef has been recognized as a peculiar supernova from its light curve and spectral properties. The object was classified as a Type Ic supernova (SN Ic) because its spectra are dominated by broad absorption lines of oxygen and iron, lacking any clear

Modeling of the Super-Eddington Phase for Classical Novae: Five IUE Novae

, 2006
We present a light curve model for the super-Eddington luminosity phase of five classical novae observed with IUE. Optical and UV light curves are calculated based on the optically thick wind theory with a reduced effective opacity for a porous ...

The radial pulsation of AI Aurigae [PDF]

, 2001
We present an analysis of eleven years of Stromgren by photometry of the red semiregular variable star AI Aurigae. An early period determination of 63.9 days is confirmed by the long-term light curve behaviour.
