Abstract: Based on the foundation laid by the h-index we introduce and 
study the R- and AR-indices. These new indices eliminate some of the 
disadvantages of the h-index, especially when they are used in combination 
with the h-index. The R-index measures the h-core's citation intensity, 
while AR goes one step further and takes the age of publications into 
account. This allows for an index that can actually increase and decrease 
over time. We propose the pair (h, AR) as a meaningful indicator for 
research evaluation. We further prove a relation characterizing the h-
index in the power law model.
