The research record divides more cleanly than most. Accretion is the spine of it — matter
falling onto a compact object, losing angular momentum, heating as it goes — and it turns up
in 73 of the 325 entries indexed on this site. The single
largest group is novae and cataclysmic variables, 90 entries,
beginning with two 1975 papers written with Giora Shaviv on the light curve of HZ Herculis
and on X-ray sources in planetary nebulae.
From there the subject widens without shifting. Papers on the stability of accretion disks
in the late 1970s lead into work on jets and on the coalescence of white dwarfs; the
white-dwarf merger papers of the late 1980s connect directly to Type Ia supernovae, which
is where the record turns toward cosmology. Thirty-three entries deal with supernovae and
cosmic expansion, and they cluster in the years when Type Ia supernovae were becoming the
instrument that measured the expansion history of the universe.
The shape of the output is itself informative. Half of everything in the index — 168 of
325 entries, 52 per cent — falls in the 1990s, the decade at the
Space Telescope Science Institute when Hubble was returning data and the supernova
cosmology results were arriving. The 1980s account for 82 entries and the 2000s for 66.
The Astrophysical Journal carries 127 of them, with Monthly Notices at 34 and
Astronomy & Astrophysics at 28; 9 reached Nature.
Collaboration is the other visible pattern. James Truran appears on 25 of the entries,
James Pringle on 20 and Noam Soker on 19 — long working relationships, not one-off
papers. Giora Shaviv, the co-author on the two earliest entries from 1975, appears
on 14 in total. Reading the index by co-author instead of by date gives a different and
more accurate picture of how the work was actually done.
The two halves of the career are not separate. Working as an astrophysicist and author at the
same institute for two decades, he took the questions the papers could only gesture at and
gave them a book each. A smaller strand is easy to miss: the question of whether the
universe is arranged so that intelligent life can appear in it. That thread surfaces in the
research and then becomes the argument of the popular books.
