Astronomical and Astrophysical Transactions Guide for Editors and Authors

Manuscripts that do not meet these basic requirements will be returned to the Editorial Office.

The following items are REQUIRED for all accepted manuscripts:

1.		File type 
The paper should be provided as a Word or TeX file. A copy of the paper in pdf format is useful for reference.

No text wrapping should be used as this causes problems if text has to be amended.

Do not use ligatures (e.g. , ﬃ and ) when word processing; please type these as separate letters (e.g. fi, ffi and fl). On converting a TeX file to Word, all ligatures are omitted.

2.	Author contact details

An email and postal address is required for EVERY author named on a paper.

One author should be designated the Corresponding Author. This person will be the contact for production queries, proofs and for readers following publication of the paper.

3.	Abstract

Every paper must be accompanied by an abstract of 100-150 word summarizing the significant coverage and findings.

4. 	Equations and Formulae
Any mathematical, chemical, or astronomical notation should be clearly marked.
(i) Mathematical 
Mathematical equations should preferably be typewritten, with subscripts and superscripts clearly shown. It is helpful to identify unusual or ambiguous symbols in the margin when they first occur. To simplify typesetting, please use: 1) the "exp" form of complex exponential functions; 2) fractional exponents instead of root signs; and 3) the solidus (/) to simplify fractions - e.g. exp x1/2
Mathtype should be used for the equations. Note that Mathtype should not be used for word processing, i.e it should not be used for the main text, the authors’ names and addresses, the references, etc.  This is because the default mode of Mathtype is italic with no spaces and therefore, if text is typed using Mathtype, it appears in italics closed up and disappears off the edge of the page! There is no need to insert spaces round symbols in Mathtype; this is done automatically.

Scalars should be in serif italic, e.g. b and B; matrices should be in serif bold roman, e.g. b and B;  vectors should be in serif bold italic, e.g. b and B; tensors should be in sans serif bold italic, e.g. b and B.
(ii) Chemical Ring formulae, and other complex chemical matter, are extremely difficult to typeset. Please, therefore, supply reproducible artwork for equations containing such chemistry.
(iii) Marking Where chemistry is straightforward and can be set (e.g. single-line formulae), please help the typesetter by distinguishing between e.g. double bonds and equal signs, and single bonds and hyphens, where there is ambiguity. The printer finds it extremely difficult to identify which symbols should be set in roman (upright) or italic or bold type, especially where the paper contains both mathematics and chemistry. Therefore, please underline all mathematical symbols to be set in italic and put a wavy line under bold symbols. Other letters not marked will be set in roman type.
5. 	Tables 

Number tables consecutively with arabic numerals, and give a clear descriptive caption at the top. Avoid the use of vertical rules in the tables. Indicate in the margin where the printer should place the tables.
6. 	References and Notes 

References: References should be indicated in the text by consecutive Arabic numbers within square brackets. The full list should be collected and typed at the end of the paper in numerical order with only one reference given for each number. Listed references should be complete in all details. Please see the examples below for style.

7. 	Figures and Tables
All figures should be numbered with consecutive arabic numbers, have descriptive captions and be mentioned in the text. Keep figures separate from the text, but indicate an approximate position for each in the margin.
Figure files should be supplied separately from the text. All figure files should be labelled fig1, fig2, etc., for identification.
All tables should be cited in numerical order.
Tables are preferred in Word format. On converting a TeX or pdf file to Word, tables usually lose all formatting, alignment, etc.
8. 	Language
The official language of the journal is English.
