Multi-temporal Earth Observation and Mars orbital imagery data with frequent repeat coverage provide great capability for planetary surface change detection. When comparing two images taken at differe...
A Change in the Lightcurve of Kuiper Belt Contact Binary (139775) 2001 QG298
Change Lightcurve f Kuiper Contact Binary
2011/10/11
New observations show that the lightcurve of Kuiper belt contact binary (139775) 2001 QG298 has changed substantially since the first observations in 2003. The 2010 lightcurve has a peak-to-peak photo...
Period Change Similarities among the RR Lyrae Variables in Oosterhoff I and Oosterhoff II Globular Systems
Period Change Similarities among RR Lyrae Variables
2011/1/11
We present period change rates (dP/dt) for 42 RR Lyrae variables in the globular cluster IC$\,$4499. Despite clear evidence of these period increases or decreases, the observed period change rates are...
A Change of Rotation Profile in the Envelope in the HH 111 Protostellar System: A Transition to a Disk?
Galaxy Astrophysics (astro-ph.GA)
