I've got the problem that everytime I run my .tex file I get the error undefined control sequence. It shows me that the error is in line 406 in my .bbl file which is a blank line. Does anyone know, where this comes from? Many thanks in advance.

Here is the part of my .bbl file that is concerned. Line 406 is the blank line between the two \bibitems:

can you show us the complete error message? – Jan 16 '19 at 14:52

It would help if you would mention which command is undefined - in case you can't see it, look in the log file. – Ulrike Fischer Jan 16 '19 at 14:52

@J.Eng That is probably only what your editor shows you. There should be more in the .log file. – samcarter_is_at_topanswers.xyz Jan 16 '19 at 14:55

A wild guess: what does happen if you add \newcommand{\apj}{The Astrophysical Journal} to your document? – samcarter_is_at_topanswers.xyz Jan 16 '19 at 14:56
@samcarter That solved it!! Thank you very much! – J. Eng Jan 16 '19 at 15:00
@J.Eng Good to hear that this solved your problem. For a complete list of macros, see e.g. here: http://adsabs.harvard.edu/abs_doc/aas_macros.sty – samcarter_is_at_topanswers.xyz Jan 16 '19 at 15:11
