My technical papers on solar astronomy can be found by searching the Astrophysics Data System.
To read my articles in StarDate magazine (a publication of the University of Texas McDonald Observatory) you’ll have to actually purchase back issues here. My articles appear in, for example, July/August 2018, March/April 2017, July/August 2005, March/April 2004. The latest one (July/August 2018) is an article about the analysis of a pair of meteorites that scientists think contain samples of brine from Ceres or a similar asteroid.
Just for fun, I wrote an article about birdwatching in Brittany’s Sept-Iles that appeared in Bird Watcher’s Digest. You can read this online here by registering for a free preview.
Read a clarification I wrote about a popular astronomy book about Pluto’s atmosphere here.
