Edits to Abstracts

    • We understand that edits sometimes need to be made to abstracts after they are submitted. We try hard to accommodate edits and changes as we lead up to the conference, but due to certain publishing deadlines we will be unable to edit abstracts after 20 September 2018.

Types of Presentations

Plenary Presentations

    • Prize Lectures
    • Invited Lectures

No other sessions or events are scheduled in parallel with plenary presentations. Plenary speakers will receive special abstract and presentation instructions from the AAS Executive Office.

Research Contributed Presentations

    • Research Contributed Oral Presentations
    • Research Contributed Regular Poster Presentations
    • Research Contributed iPoster Presentations

For those that are within one year of receiving your PhD there will be two options in the abstract submission site under the Regular form. Check the first box on the "Abstract Title and Body" step if you meet the requirements and are interested in having your talk recognized as a PhD talk. You may also check the second box if you would like to request a longer, 15 minute talk time.

History Contributed Presentations

    • History Oral Presentations
    • History Poster Presentations

Education Contributed Presentations

    • Education Oral Presentations
    • Education Poster Presentations

Regular, history, and education oral presentations, are arranged by topic and are scheduled in 90-minute sessions. Plan to allow five minutes for the talk and three minutes for Q&A.

Regular, history, and education posters allow far more time and flexibility than the corresponding oral presentations. Posters are arranged by topic and will be on display for the entire meeting.

Submission Process

Abstracts must be submitted through the presenting author's record. Co-authors are not eligible to substitute as the presenting author. The presenting author will be notified once the schedule has been determined.

Presentation Guidelines and Tips

Poster Presentations

Poster Printing in Knoxville

The DPS is not offering onsite poster printing. If you're interested in printing your poster near the meeting venue, the closest commercial printer is the FedEx office at 2010 Cumberland Ave.


Posters allow far more time and flexibility and are the default presentation type. Posters are ideal for using charts, graphs, or detailed visual aids. The poster area serves as the meeting’s social center.

    • Your poster must fit within the 44" x 44" area.
    • Poster abstracts are sorted by topic.


    • When preparing your poster, remember to use bold graphs, photographs, figures, and tables. Include a title and the names of authors in large type. Text should be large enough to be legible from a distance of three to four feet, ~ 20 point font. Keep the poster simple and easy to read.
    • There is a good article on preparing an eye-catching poster at, Presentations: Billboard Science.
    • Consider posting a photo of yourself with your presentation.

Oral Presentations


To avoid too many oral sessions running simultaneously, the number of oral presentation time slots is limited. Oral presentations can be changed to posters if there are no remaining slots. All authors whose abstracts are changed will be notified.

    • Oral presentations are 10 minutes total - five minutes for the presentation, three minutes for open discussion, and two minutes for speaker transition.


    • When preparing your presentation, we suggest a maximum of three slides for a five-minute talk. Slides should be uncluttered and easy to read.
    • Practice a few times so the presentation fits comfortably into the five-minute slot.
    • Read the AV instructions.

Publication of Abstracts

The meeting and abstract schedule are published in various formats:

    • Paper Abstract Book – Available for purchase during registration, includes full abstract text.
    • Online PDF of Abstracts – Available two weeks prior to the meeting; includes full abstract text.
    • Astrophysics Data System (ADS) – Full abstracts are sent to ADS and typically published two weeks prior to the meeting.
