TRANSCRIPT
Early career
• Taken by his father to space travel lectures 1952• 1956 study at Zeeman lab, Amsterdam with
Klinkenberg (“old fashioned spectroscopy”)• 1959-1961 Army service, study of radio-active
fall out• 1961-1970 Rijnhuizen, study of gas discharges
and hot fusion plasmas; thesis 1969 with C. Braams and H.G. van Bueren
SRON
• SRON (predecessors) founded 1961 by Kees de Jager
• Bert Brinkman had solar X-ray observations
• Rolf Mewe appointed at SRON 1970: simple task: “develop X-ray spectroscopy”
• Rolf’s own words in 2000: “I was so naïve to promise to try this”
The ANS satellite
• First Dutch Satellite• Launch 1974• Soft X-rays (0.25 keV)• Discovery of X-rays
from Sirius (Nature paper Mewe et al. 1975)
Chandra
• Rolf involved in making science case and simulations for AXAFChandra
• LETGS his favorite spectrometer
• Won lottery to be at launch of Chandra
Other satellites
• ANS 1974• Einstein 1978• EXOSAT 1984• YOHKOH 1991• EUVE 1992• ASCA 1993• BeppoSAX 1996• Chandra & XMM-Newton 1999
Spectroscopic codes
• 1972 Mewe
• 1975 Mewe-Gronenschild
• 1985 Mewe-Gronenschild-van den Oord
• 1990 Meka
• 1994 Mekal
• 1992 SPEX
Most cited X-ray papers (ADS)

He-like line diagnostics
• Work on He-like triplets with Hans Schrijver 1975-1980
• Recently followed up with Delphine Porquet et al.
DEM modeling, stellar work
• Collaboration with many people
• Janusz Sylwester• Karel Schrijver• Manuel Güdel• And many others
Rolf and his Army
• Thanks to alternative civilian service, well-educated conscientious objectors served Rolf as unpaid data-aids:
• Frans Alkemade• Remco van der Rijst• Max Duijsens
Meka
• Development triggered by needs of SNR work at SRON-Leiden around 1990
• Restructuring the Mewe-Gronenschild-vdOord code and improving continuum
• NEI effects
