Hit papers significantly outperform the citation benchmark for their cohort. A paper qualifies
if it has ≥500 total citations, achieves ≥1.5× the top-1% citation threshold for papers in the
same subfield and year (this is the minimum needed to enter the top 1%, not the average
within it), or reaches the top citation threshold in at least one of its specific research
topics.
The Provenances of Asteroids, and Their Contributions to the Volatile Inventories of the Terrestrial Planets
This map shows the geographic impact of C. D. K. Herd's research. It shows the number of citations coming from papers published by authors working in each country. You can also color the map by specialization and compare the number of citations received by C. D. K. Herd with the expected number of citations based on a country's size and research output (numbers larger than one mean the country cites C. D. K. Herd more than expected).
This network shows the impact of papers produced by C. D. K. Herd. Nodes represent research fields, and links connect fields that are likely to share authors. Colored nodes show fields that tend to cite the papers produced by C. D. K. Herd. The network helps show where C. D. K. Herd may publish in the future.
Co-authorship network of co-authors of C. D. K. Herd
This figure shows the co-authorship network connecting the top 25 collaborators of C. D. K. Herd.
A scholar is included among the top collaborators of C. D. K. Herd based on the total number of

represent the number of papers authors have co-authored together.
Node borders
signify the number of papers an author published with C. D. K. Herd. C. D. K. Herd is excluded from
the visualization to improve readability, since they are connected to all nodes in the network.

Rankless uses publication and citation data sourced from OpenAlex, an open and comprehensive
bibliographic database. While OpenAlex provides broad and valuable coverage of the global
research landscape, it—like all bibliographic datasets—has inherent limitations. These include
incomplete records, variations in author disambiguation, differences in journal indexing, and
delays in data updates. As a result, some metrics and network relationships displayed in
Rankless may not fully capture the entirety of a scholar's output or impact.
