Determining the Rotation Periods of an Inactive LEO Satellite and the First Korean Space Debris on GEO, KOREASAT 1 [PDF]

Journal of Astronomy and Space Sciences, 2016
Inactive space objects are usually rotating and tumbling as a result of internal or external forces. KOREASAT 1 has been inactive since 2005, and its drift trajectory has been monitored with the optical wide-field patrol network (OWL-Net).

Light Curves of Supernovae [PDF]

International Astronomical Union Colloquium, 1996
Although emerging from a range of progenitor stars and the product of different explosion mechanisms the light curves of the various supernova types are shaped mainly by radioactive power. Core-collapse supernovae have in addition early peaks from shock breakout with a subsequent cooling phase and massive extended stars a recombination (plateau) phase.

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.

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 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

starry: Analytic Occultation Light Curves [PDF]

The Astronomical Journal, 2019
Abstract We derive analytic, closed form, numerically stable solutions for the total flux received from a spherical planet, moon, or star during an occultation if the specific intensity map of the body is expressed as a sum of spherical harmonics.

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 ...
